Thanks for the tips, I've tried them, but no success...seems that 3.0.8 is buggy a bit

Congrats on that! Well deserved!

just as a late question:

what are deep shadow maps?
is it the same like shadow maps, which are in the rendersettings?

Good job!

Shadow map = 2 color-only shadow map, no transparency
Deep shadow map = Pixar's original "with tranparency" shadow map format (pdf)
Detail shadow map = mental image's version of deep shadow maps
Volume shadow map = Softimage's GUI name for MR detail shadow map

hey thanks! (and good job too for the area post!)
i don't find a way to activate deep shadow maps in 3delight...
it should be possible, but i don't find something in the docs nor the ppg of 3delights render settings...

using the maps in the shadow maps tab renders for ages...

Hi,

you enable the deep shadow maps in the same way as with Mental Ray, in Shadow Map tab of light's PPG. For colored deep shadow map, procedure is:
1: in global render options, under Shadow Maps, enable 'Surface' for shadow map shaders
2: apply a 3delight's 'Hit Mode' property to object or group, set 'Run Material' for Shadow Rays
3: put something into the shadow slot in rendertree, let's say Color_Save_State, or Constant material.

cheers

I'm really having a hard time getting my head around 3Delight rendering. Are there any tutorials or can someone provide a scene I can study?

Thanks.

There is an older tutorial series made by "Chinny" (Jason Brynford-Jones) from Softimage, but he uses XSI 6.5 and an older version of 3Delight for Softimage as well. Still worth watching as a basic introduction IMHO

CSG

This is a render-time CSG ( constructive solid geometry, Boolean operations ).

Speaking of CSG... anyone know if there is a trick to getting it to work right, beyond the description in the user manual? When I set up a simple test, with two intersecting spheres, (sphere B has the 3Delight CSG property, set to subtract, and is a child of sphere A), the "cut" surface will only respond to ambient light (no shading), and is controlled by sphere B's material.

I'm using SI 2012 SP1 (64-bit) and 3Delight 3.0.11

Hi,

as far as I can recall (didn't played with CSG since this scene), setting XSI geo approx to more than zero, or using a Renderman subdivs ( 'smooth subdivision threshold' on zero), made it to work as expected.
Anyway, here is the thread in 3delight forum, about CSG and related stuff. There is also a link to XSI model I've created for these CSG renders.

cheers
