Hi there,

I'm making a custom collection of blasters in Blender, when exporting OBJs from Blender to Asset Forge, the materials have a much darker color, and the thumbnails look darker too compared to the vanilla pieces.

I copied the hexadecimal value of the material color from ASF into the BaseColor channel in Blender's BSDF shader for all 3 materials used by the blaster pieces (_defaultMat, metalDark and dark), also copied metallic and glossiness values. Somehow, Blender seems to convert the colors when exporting to OBJ, I have no clue why or how.

So my question is: how to make colors look exactly the same when exporting OBJ from Blender to Asset Forge.

Software Used:

• Asset Forge 2.0 preview-1c (Deluxe)
• Blender 2.82 with EEVEE renderer

Steps to reproduce:

• In Blender, create any object (eg cube) and create a material named metalDark
• In Asset Forge, place a random blaster piece, go to materials, and select the metalDark material
• Copy color, metallic and glossiness values from ASF to the material in Blender, setting Roughness to the inverse of glossiness
• In Blender, export the object as OBJ with the default export settings and add it to a custom ASF collection
• Re-open ASF with a clean scene, place the newly added object (should be placed first to initialize the materials)

I have a hunch that the problem is in the MTL file that blender exports along with the OBJ.

Here is the MTL file from one of my models (exported from Blender):

newmtl _defaultMat

And here is the MTL file generated by Asset Forge when exporting a vanilla blaster piece

newmtl metalDark

newmtl dark
