4. Can I use an external rendering engine? Again, this is a feature that can be added by third-party developers who choose to do so. Such extensibility, according to Adobe, is possible via the new API.
I’m wondering how, or if VRay materials would be brought into CS3. Anyone?
It appears you can paint on a 3ds format - it probably works similar to something like Deep Paint. Perhaps it will only work on bitmaps.The formats it supports are:
“Photoshop Extended supports common 3D interchange formats, including 3DS, OBJ, U3D, KMZ, and COLLADA, so you can import, view, and interact with most 3D models.”
The other thing which I have read is that the new CS3 will NOT be 64-bit. Correct me if I am wrong, but I’ve read that somewhere and have yet to prove this contrary.
