Hopefully adding support to obj import mtl parsing to support a flag for diffuse texture having an alpha pass. "bjs_diffuseHasAlpha 1"

So you want to go with a custom parameter? This does not seem scalable

Let me review the mtl file structure and and see if there is a parameter that covers the diffuse having an alpha. I'm pretty sure there is not, so my thought would be you could edit your mtl after export.
What thoughts do you have?

I get your point but this is kind of not convenient
I would perhaps prefer loading the texture and trying to check if there are alpha data
But your solution is also acceptable

roger that! Let me whip up a method for that, then maybe we can compare and then get input from others?

Hi @Pryme8 , |

I have no way of testing this and have just kinda given up on the idea... so y'all can delete this PR. sigh sorry. |
