Hey all...
I am currently trying to learn the mentalray SSS_fast_simple and fast_skin shaders... however - I keep running into the same problems with both - when I set up the shader, with the lightmap connected to the SG, and after I make the mentalray_texture node from the shader to connect into the lightmap as well as the SSSshader... I set the texture to be writable, 800x800, 32bit and to save to C:/temp folder. (so far i've followed the Gnomon SSS video tutorial from www.thegnomonworkshop.com verbatum...)
However -here's where problems start.
When I kick a render - it seems to work from frontal lighting situations, but anytime there is backlighting - to show off the SSS effect... it doesnt work. Furthermore - here's why - in the script editor this error comes up that MentalRay could not write the texture file (the one connected to lightmap and SSSshader)...
(I also noticed the MentalRay texture node has a red X through it... is it missing or something? Do i need to reinstall maya? Am I not doing something? or was something excluded from the Gnomon tutorial? will gas prices ever go down?)
Anyone run into this problem or have any ideas how to fix?
Any help is greatly appreciated!
Thanks!
