Particle systems visible behind object alpha 0.000?

Support Basics & Interface

Is there a way that I can see paricles behind an object that has an alpha level of 0.000?

Thanks :smiley:

Turn on ZTransp for the sphere. If you see a specular, turn Spec to 0 or turn on OnlyShadow.

Ztransp works. However its not giving me the same effect as RayTransp. Because I need to use IOR. Is there anyway to make it work for Ray Transp?

parent a cube/sphere/face/anything with a halo texture on it to your emitterā€¦ currently, pure halos are not seen by the internal raytracer, because they are the result of post-pro if I have well understoodā€¦
so if you want particles to be reflected, refracted, seen through raytransp objects, turn them is something ā€œsolidā€ :wink:

yeah, particles [halo materials] donā€™t show in raytraced portions of images, so youā€™ll need to use an environment map instead

you can do some fake refractions using an environment map

if the blender 2.0 book was online, Iā€™d be able to show you the tutā€¦

The Blender 2.0 book is online.

Scroll down to the part where it says ā€œRefraction in Solid and Hollow Glass by Randall Rickertā€:

The .blend files the document talks about should be in one of these zip files:

If particles are the result of post-pro, why would they show up in envmapsā€¦? I hope it works for you!

Hi !

Have you tried the Unified render ? It can solve some problems with halos and Raytracingā€¦ I used it in the past for a laser beam made of halo, which couldnā€™t be seen through a glass showcase, using the simple render.
