How do I bake an additive texture so that it looks the same when applied in Roblox?

  1. I want to bake an additive texture from 3D software Blender, combining lighting or glow effects into a single texture map. Then, I want to import that baked texture into Roblox and apply it to my model, so that it keeps the same glowing or bright effect as seen in the original render. My goal is to make the texture look as close as possible to how it appeared before baking, especially the additive or emissive look.

  2. Texture:

Geometry Nodes:

I modified the material properties to make the texture or model look additive:

Appearance of Model:

So do you have any idea how I can bake the texture with the same appearance including the effects from Geometry Nodes and modified material properties and then put it in Roblox?
