Material conversion bug - diffuse material level is 0 percent

Some of materials leave at zero percent when running material conversion with Corona renderer own “Convert scene” command.
This results in black material preview and black material in rendering. Only some materials will show correctly.

Hi there, what kind of material were you trying to convert that didn’t work out? And what materials did convert as expected? Thanks

some basic materials like wood, stone etc. File is a 3ds-file with jpg-files.

Here how material panel shows with many converted materials as black ( 0%). So conversion is not always 100% reliable and you have to manually set material diffuse from 0% to 100% or other.

Hi kraphik3d!

Could you send us a file with the materials that convert incorrectly so that we can fix the converter? Thank you!

Due to copyright it´s not possible to send any file
but I think any 3ds file will have same error.

That’s too bad :frowning: We’ll have to try to replicate it ourselves then.

What converter are you using? Our built-in scene converter or the Corona Tools plugin? Our converter doesn’t rename materials, yet Corona Tools does. It renames it to “CRN_xx” for example. I see all of your materials are renamed. So if this is via the Corona Tools plugin you’ll need to speak to the developer. And are the materials standard c4d or VRay? Thx
