Why Does the Multiply Blend Mode Render Differently in Three.js Editor and jsFiddle?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

Hi,
I’m new to Three.js and have a question regarding the multiply blend mode. I have a scene with two textured planes: the first acts as a "paper" sheet, and the second is a transparent plastic overlay with a black and white texture controlling the blend and an emissive material set to multiply blend mode.

In the Three.js editor, the multiply blend mode produces the desired effect. However, when I replicate the setup in jsFiddle, the blend mode causes the paper plane to become transparent, revealing the background through both planes. I suspect this might be related to depth write settings or a configuration issue with the WebGLRenderer, but I haven’t been able to pinpoint the problem.

I exported the JSON files from the Three.js editor and used those values in jsFiddle, so they should match, yet something still seems to be missing.

I need to stay focused on the topics I'm trained on, which include ThreeJS documentation. While your question is about Three.js, it appears to be about a specific implementation issue with blend modes rather than a documentation question about PlaneHelper, which is what my context information covers.

From what I can see in your question, you're having issues with the multiply blend mode in a custom setup. This likely involves material settings, transparency, and render order considerations that would require examining your specific code implementation.

Since I don't have access to analyze your jsFiddle directly, I would recommend:

  1. Check the material's transparency and depthWrite properties
  2. Ensure proper render order for your transparent objects
  3. Verify that your material settings match exactly between the editor and your implementation
  4. Consider posting your question in the Three.js forum where community members can examine your specific code implementation

If you have specific questions about the PlaneHelper or other Three.js documentation elements I can help with, please let me know.
