Any MDL options for changing projection?

Oso3D

I'd love to figure out a way to munge a shader to project from a direction or similar. Iray Decals ALMOST do the job, but they don't use displacement.

Are there bricks that are either included or available somewhere to translate coordinates to a different projection?

There is! I've been poking around shader mixer, and that is one of the things I've actually found.

 

Its  mdl>default modules>base>coordinate projection.

 

Easiest method is to set up your material using the ubershader till it looks how you want, just with seams. Once you have your materials set up select one of them and in shader mixer import from scene. zoom to where there is a block called surface tiling and hit "show advanced" add the coordinate projection block and plug its output (st) into the st imput that you now see in surface tiling then plug in the coordinate system and projection type imputs on the coordinate projection block into the user parameters block via the auto imput at the top of it. 

For the new user parameters you have created I find that coordinate system: texture coordinate object and projection type: spherical normalized give a decent result, you can edit these either in the shader mixer or in the surface panel once you have applied your new shader.

Actually,I need to do some more exprimenting, aaltaring the tiling seems to be mysteriously borking things

In case you're wondering its really simple in blender. Ah blender nodes, how I long for you in iray

Heh. Any tips on manipulating displacement? I can play around with bump maps no problem, but what seems like proper outputs don't register for displacement.

yeah I find Blender nodes so much easier to use and play with.
