Hi everyone, I’m building an editor that allows users to design their own sweaters. This is done by providing blank models and allowing users to change the color, add text, upload prints, etc. [Screenshot 2023-07-03 at 18.09.04] We also want to give users the option to download the modify 3D mo…

@vis_prime on the Discord helped me figure out the problem of the decals looking fizzy. The draco export probably causes an overlap in vertices and leads to the distortion. The solution is to loop over the vertices and move them a little further away: let offsetAmount = 0.1 // adjust this value (…

For the color issue, you may find some clues in this thread [image] Updates to Color Management in three.js r152 Discussion The upcoming release r152 will contain changes affecting color and lighting. These updates enable a “linear workflow” by default, for be…

yeah ,read the above post and experiment with texture’s encoding/colorSpace , general rule : diffuse/emission textures should be srgb rest all should be in linear encoding/colorspace and for the text thing stick to meshStandardMaterial for all the meshes which you will export as it’s the most wide…

It’d be helpful to see what the material is that you’re exporting – what type, what parameters, and how are any textures loaded.

Thank you for everyone’s input! I took a step back and updated to r154 (was r145 before) and that mostly fixed the color issues. The decals had to be refactored a bit and I changed the material, as suggested. It’s working quite well now :slight_smile: There might still be a hint too much metalnes…

Hey Daniel, I am so glad I found your question here because I have been working on exporting into a GLB/GLTF as well and the decal distortion/z-fighting has been doing my head in too! Literally been pulling my hair out trying to fix the decal. Did you settle on a simpler solution or in the end was …

Most of it was just updating to a newer version of three. If you read the changelogs between 145 and 154, there is one in there that specifically addresses this. I can’t remember exactly how I refactored the decal at the time, but here is what it looks now: <Decal position={[x, y, z]} …

Hey @Daniel211 , I am working on something similar and I am experiencing issues with rendering the .glb model with the decal applied to it. Could you maybe share the part of your code that handles exporting in more detail? I have noticed you’ve used the useRef hook to get the modelRef for the export…
