View Full Version : color bleeding 3Delight
id like to render this scene from escape studios "RenderMan Certified Courseware" with 3DL...
but i dont get the color bleed to work...
im using the envlight2 shader in the ambientlight, but i get an dark grainy result...
converted an hdri image to .tdl for the envmap...
any ideas what im doing wrong...?
are there any guideline how to setup a scene for 3delight..?
all these light and geo attributes are really confusing for me...

You need to add geometry attributes to ..mm.. your geometry :)
As you are using the raytraced way, you need to make your geometry visible to the env shader.

with the envlight2 you can't get bleeding magically..
Envlight2 will provide some shadowing effect and is also relate to your env setup.
You can get some finalgather with the indirectlight + photons (load the example file provided with the sw) - You can get bleeding effect with some custom shader or with photons.
Check 3delight forum page form more :)
And also look here (http://3db-site.com/html/RSL_exercises/rsl_exercises_gather.php) for some programming basics
Take a look over here (http://www.deathfall.com/forums/showthread.php?p=105753#post105753) for some more stuff
.. and sorry for not being more specific but i'm in hurry, cya.

Is there a reason you're using raytraced methods instead of point clouds?
no there is no reason... these are my first steps with 3delight...
so i try everthing i get on infos...
how to avoid raytracing..?
when do i use taytracing... there is no big tickbox for raytracing like in other render engines...
keep the suggestions coming...
searching now in a new direction...
tried this tutorial from Jorge and ints working fine...
but i have no succsess with the second one...
nothing is happening... i get the pointcloud but if i try to read it with the second shader nothing changes...
any ideas or other ways to do it.?

Yeah, you can do that using light shaders or surface shaders. It depends on how you feel more comfortable :)
Here's a lot of info about the ways you can do it and some shaders too.
