Blender texturing and exporting questions

[Theothoras (Nairobi)]

I got a few questions about exporting and blender in general.

1. Should i texture in blender or in roblox? If in blender, how do i match the lightning from roblox in blender, because usually when i model in blender, the color in blender looks different than in roblox.

2. Is it worth combining parts in blender when exporting with (CTRL+J), to make them one mesh? Usually that causes problems for me and i don’t know if im saving anything by doing so.

3. FBX or OBJ and why?

4. When i export as fbx, the image texture exports fine, but if the mesh has a base color, it exports blank. How do i fix this?

1. I would recommend texturing in blender, but you can do it in studio if you want to use materials or solid colors.

2. if you want it to be one mesh instance in studio then yes.

3. FBX, It supports much more features. Most notably separate objects in blender will be separate instances in studio.

4. You should not be using base color if you are planning on exporting it to studio. instead you should be changing the mesh color in studio.

So i should only use blender for textures and image colors and use roblox studio for base colors?

I don’t fully understand your question, but for example say you have this tree model in blender.

In studio you want it to look like this but don’t want to use a texture. In this case you would separate the differently colored parts into separate objects.

Once you do that you can export it as an FBX file into studio, but it will be gray. All you have to do is color the separated objects in studio and then your done!

Now if you want your tree to look like this you will need a texture.

Yeah that was my question, but also i wanted to ask why do base colors don’t export to roblox? Like if you color a cube in blender with 1 base color, why does the color disappear when exporting to roblox? It imports just grey, while if you use a image texture to color (like a color grid or smth) , the texture stays?

Most file formats such as FBX and OBJ do not support base color from blender; afaik only .blend supports it.

So technically any game engine i use (UE5, Unity, etc.) wont support the blender base color? Just so im clear, this is the base color im talking about.

tbh I’ve never tried it so I’m not 100% sure, but roblox doesn’t support it for sure.
