No problem!

Just create to nodes and join them together this is the only way around that I'm afraid as this one is generated along curves :) trust me we tried XD

Happy to help

haha, no worries :)

Thank you Rob!

No problem!

Yer sorry about that was never intended for that purpose :)

Yes, we charge for our time and to feed our families. I don't think there is anything wrong with that.

No problem we do now have a geometry node to do all this now as well - ua-cam.com/video/TMqRT2i-ngI/v-deo.html

Welcome!

You're welcome!

The error "[SM6] (Node RotateAboutAxis) Cannot cast from smaller type float2 to larger type float4" indicates a type mismatch in your shader code within Unreal Engine 5. This issue typically arises when there is an attempt to convert a smaller type (like a float2) to a larger type (like a float4) without the correct method or function. To address this issue, you need to ensure that the data types being used in your shader operations are compatible. Here’s how you can troubleshoot and potentially fix the problem: Steps to Resolve the Error: Check the Node Inputs and Outputs: Ensure that the RotateAboutAxis node is receiving the correct data types. Specifically, check if you are passing a float2 where a float4 is expected. Use Proper Type Conversion: If you need to convert a float2 to a float4, you must do so explicitly. For example, you can expand a float2 to a float4 by adding the necessary components. In shader code, it might look something like this: hlsl Copy code float2 value2 = ...; // Your float2 value float4 value4 = float4(value2, 0.0, 0.0); // Converting to float4 by adding zeroes for the missing components Modify the Shader Code: If you have access to the shader code, look for the part where RotateAboutAxis is used and ensure the inputs are correctly typed. Here’s an example adjustment: hlsl Copy code float4 position = ...; // Ensure this is a float4 float4 axis = ...; // Ensure this is a float4 representing the axis float angle = ...; // This can be a float representing the rotation angle // RotateAboutAxis expects a float3 or float4 depending on the context float4 rotatedPosition = RotateAboutAxis(position, axis.xyz, angle); Check Material Graph Connections: In the Material Editor, verify that the connections to the RotateAboutAxis node are correct. Ensure that the inputs are appropriately set to float4 or use conversion nodes to match the expected types. Use Shader Function Nodes: Sometimes using built-in functions or nodes can help manage type conversions automatically. Ensure you are using the correct functions for your operations. Example Correction in Material Editor: If you are using the Material Editor and not directly coding HLSL, follow these steps: Locate the RotateAboutAxis node. Check the inputs connected to this node. If you have a float2 connected, use a MakeFloat4 node to convert it: Create a MakeFloat4 node. Connect your float2 to the XY inputs of MakeFloat4. Set the Z and W inputs to 0.0. Connect the output of MakeFloat4 to the RotateAboutAxis node. By ensuring the types are correctly matched, you should be able to resolve the casting error and proceed with your skybox creation in Unreal Engine 5. If the issue persists, double-check the entire shader network for any other type mismatches or incorrect node connections.

​@@3DTudor This is a little confusing. I'm using a fresh UE 5.4.2 install, but my absolute World Position looks different. I followed the exact steps and have the same node tree. While I understand the error itself, I am still struggling to fix it. I tried operations like UVtoLongLat, LatLongtoUV, and MakeFloat4 (which does not have a W input, but A instead). Plugging Absolute World Position XY into MakeFloat4 XY and setting Z and A both to 0 results in:[SM6] (Node RotateAboutAxis) Cannot cast from larger type LWCVector4 to smaller type LWCVector3. Also, I am not sure how one would check the shader code itself. I have experience in Maya but am new to UE5.

What I mean is the fact that its around the hour mark to learn a fire geometry node :)

Thanks for this we are always learning :)

Reach us via our email address please.

@@3DTudor Kindly check your mail inbox sir. I've texted you with a proof sir

Roughness or normal grunge textures, depending on the size of scratches :)

You're welcome!

Thanks

Thank you! Cheers!

Glad it was helpful!

This is a crazy amount of stuff to answer and I will need some time to look at all this I will put a response here today sometime :)

1. Yes, you are correct. You can convert a model created with Geometry Nodes in Blender into a solid mesh and export it as an .fbx file for use in Unreal Engine 5 (UE5). Here’s how you can do it: Convert Geometry Nodes to Mesh: In Blender, select the object created with Geometry Nodes. Press Ctrl + A (Apply) and choose Make Instances Real. With the instances now real, convert them to a mesh by pressing Ctrl + A again and selecting Convert to Mesh. Export as .FBX: Select the mesh you want to export. Go to File > Export > FBX (.fbx). In the export options, make sure to select the appropriate settings for your project, such as applying modifiers, exporting only the selected object, and ensuring that mesh smoothing is set correctly. Click Export FBX. Limits or Restrictions: Complexity and Performance: Very complex geometry can lead to large file sizes and may impact performance in UE5. Optimize your geometry where possible. Modifiers: Ensure all modifiers are applied before export, as non-applied modifiers may not translate correctly into UE5. Textures and Materials: While the mesh itself will export, you will need to re-assign materials and textures in UE5 as Blender’s material system doesn’t directly translate to UE5’s system.

2. Yes, it is possible to use hair made with Blender's new Geometry Nodes system in game engines like Unreal Engine 5, but the process is extremely complex and requires several steps including converting the hair to a mesh, optimizing it, and then exporting it. There isn't much detailed information available on this topic currently, and your channel is among the few covering these advanced features.

3. Yes, if you convert curves to meshes in Blender, you can export them to Unreal Engine (UE) without the need for any specific addons. Here’s how you can do it: Convert Curves to Meshes: Select the curve object in Blender. Press Alt + C or go to Object > Convert to > Mesh from Curve/Meta/Surf/Text. This action will convert the curve to a mesh. Check and Edit the Mesh: After conversion, it’s a good practice to inspect the mesh for any issues that might have arisen during the conversion process. Edit the mesh if necessary to ensure it meets your requirements. Export the Mesh: Select the converted mesh. Go to File > Export > FBX (.fbx). Configure the export settings to ensure all transformations are applied and that only the selected object is exported. Click Export FBX. Import into UE5: Open your UE5 project. Go to the Content Browser, right-click, and select Import to /Game. Navigate to the exported FBX file and import it. Make any necessary adjustments in UE5, such as assigning materials or tweaking mesh properties. Additional Resources

4. Yes, it is possible to export animations made with Geometry Nodes from Blender to Unreal Engine 5 (UE5), but the process can be quite complex and involves several steps. Here’s a high-level overview of how it can be done: Bake the Animation: First, you need to bake the animation to ensure all the procedural effects are captured as keyframe animations. Select your object with the Geometry Nodes animation. In the Timeline or Dope Sheet, use the Bake Action feature (Object > Animation > Bake Action). Convert to Mesh: Similar to previous steps, ensure all instances created by Geometry Nodes are made real and converted to mesh. Select the object and press Ctrl + A to make instances real, then convert them to a mesh. Export as .FBX: Ensure all your baked animations are correctly applied to the mesh. Select the animated mesh and go to File > Export > FBX (.fbx). In the export settings, ensure that you check Bake Animation to include the animation data in the export. Import into UE5: Open your UE5 project and go to the Content Browser. Right-click and select Import to /Game. Navigate to your exported FBX file and import it. In the import settings, make sure to import animations. Obstacles and Considerations: Complex Animations: Highly complex animations might not bake correctly or could result in large file sizes, which can impact performance. Material and Texture Adjustments: Materials and textures will need to be re-assigned and adjusted within UE5 as they do not always translate perfectly from Blender. Limited Tutorials: As you mentioned, there are limited tutorials specifically for Geometry Nodes animations, so a lot of experimentation and problem-solving might be required.

Thanks :)

hope so!

We are fine thanks for the invite though.

Glad to hear it :)

we have videos on these as well latest one will be out today here - ua-cam.com/video/2kbYQtzh8cU/v-deo.html

As far as im aware we are not even on this site so it sounds as if someone has stolen our content and put it on there. If you could be more specific about the content that would help :)

@@3DTudor Haha, definitely not stolen. As far as I am aware they're integrated Packt courses for our in-house learning central at work. I highly doubt a big organisation like my work would subscribe to illegal stuff :)

@@FuadAbdi-SRG phew you are right we do work with packet :) ok will let packet know that they need to upload the resource pack and should be up today :) what course is it please ? is it this one the blender bootcamp

@@3DTudor Hi, yes correct. The bootcamp one :)

@@3DTudor Still nothing on there :(

You can use obect > convert > mesh, to set it up as a simple mesh :)

haha just trying to think of things that will help people and what i would struggle with myself :)

We need to branch and do some dystopian stuff XD

At the end of the day, if you find something that works well for you, and is efficient timewise, then use that. Designing in UE5 would be great as you wouldn't need to switch between programs and you could work directly with lighting as well which greatly effects one's greyboxing. But again, it really is up to you :)

haha, glad you like it ^^

Right on!

Glad it helped!

No worries!

It might have something to do with origin point offset, try setting origin point to geometry and seeing if it fixes it :)

Hi, you can check our free content on artstation as well. Here's the pack - www.artstation.com/a/20966706

Almost all videos I found do this. They talk about free ad ons and materials but they all end up linking to $50+ add ons that are absolutely unecessary and nothing to do with what I need for personal use.

@@SloRush This is why I perfer mine-imator

A lot of memories were formed there :)

With a little more options and tools, it does create geometry, yes

@@3DTudor messing with it, I found that you can't edit booleans once the mesh is created unlike geometry (I will still test more)

Haven't tried 3D Coat personally, but that sounds really cool actually :)

Make sure to hit the bell notification so you would get informed whenever we upload :)

Thanks :)

Glad to hear it!

The rest is based on reflection probes, with the right environment and reflections, it'll look great :)

With a little bit of post-processing using a compositor. We basically put a background image positioned to fit the camera shot :)
