HiHi. You could do it in window :D . It would be nice to see a tutorial on the workflow if you like :) .

Torque's PBR is evolving right now. Tutorials might be a bit premature :)

The links below are a good place to start learning the PBR workflow. Azaezel and lot's of others have posted bunches of links here and elsewhere.
I'm slowly working my way through about 10 different resources myself.

You can have some fun playing with PBR workflows right now with the trials of Allegorithmic's tools.

Lot's of reading to do. :D

Just playing around with the PBR branch whilst I study it's mysterious inner workings :)


Saved the grayscale roughness and metallic maps output by Bitmap2Material to RGB8 in Photoshop
Note the roughness .a and the metallic .r channels are selected in T3D
Downloaded Azaezel's PBR branch zip on 8.19.15
Screenshot is OpenGL

Link to the outputs and original main input texture https://www.dropbox.com/s/nwobyd10k7wm2 ... t.zip?dl=0

...And

Let's try Photobucket.

Can you get to the zip file from Dropbox?



Cheers!

Looks like I missed a spot on the roughness -> smoothness labelling. Try inverting that channel. (substance spits it out as rough = black, smooth = white)

You have the roughness mapping perfectly.
Makes me want to do a UE4 SciFi hallway style demo.

Picked up Bitmap2Material a few days ago. Most fun I've had in a while.
Wife says I'll have to wait on Substance Designer + Painter ... /tantrum

Ok. Next time I get a chance to come up for air, will try and slip in a tickbox for flipping that. Probably pattern it after https://github.com/Azaezel/Torque3D/com ... 56e72d4aa7

hmmm... not you They don't show up in Chrome for me either..
First time I used Dropbox for pics, not pro.
They're supposed to be visible to anyone with the link, according to dropbox, showed for me on Firefox, the browser I log in on.
