Getting translucency halos to work.

Support Basics & Interface
1

I have a plane, and on that plane, I have a textured window. I have another texture that is a translucency map and that is set to translucency and not col.

Now, the problem is, I have a halo (spot) lamp behind it, and I am doing a night scene, and I am trying to get the halo to shine through the window. The halos work perfectly without the window, and I really need the window.

I have tried everything I can: turned on “shadow button,” put all of the alpha to zero, reversed the trans. map, turned on transhadow, turned down SpecTra to zero, searched through the elysiun.com forums, turned the spots on “layer” and put those objects in that layer…

Is it possible to get the halo to shine through?

I thank you in advance for any help you might give me. :smiley:

no, not in a way it should

if your window has ztransp on and unified renderer is off, it may

too my knowlage the halo lights arn’t raytraced and traceshadow are, so you won’t be able to use a alpha map with the halo light, you’ll need to model the window

4

Try turning off shadow tracing for the window and it should effect the halo

i had some hard time with halo recently, i can tell shaped halo is difficult to get if not impossible. even with halo sample to 1 it didn’t work… i was lost cause this feature worked very well in 2.28.

well, I can’t get it to work, and I guess it isn’t that important…

thanks anyway, though!

what feature?

the shaped halo. you know to do a hole in a plan and put a halo spot behind, you can see a volumetric halo comming from the little hole. I can’t do it anymore.

You need to use Buffer shadow, not raytraced shadow. And Buffer shadow do not take transparency into accound.

I know all this theeth, but it give wierd result or it is me?
like i see a halo but it juste pass thougth the mesh whitout even calculating the shadowed halo. playing with the clipping value and it appear a bit…
ho damn i’ll stop bitching on this. i suppose i cannot set a halo lamp anymore.

i can get it to work in 2.32, all i do is
1 make lamp, set it to be a spotlight
2 turn on halo, set halo step to >0
3 make sure that the object is between the clip start and clip end
4 render

I’m trying to figure out how to do the same thing. I’m going to be using movie files (originally green-screen people, with transparency calculated in After Effects) and I want the halo to go around the people, not around the plane that has the texture. I realize that you all just said it was impossible, but can you think of any alternate way of doing it, or know of any plugins, or do any of you have enough weight in the Blender world to have a feature like this added in the future?

Thanks,

You must use your translucency texture as a texture of the Spot lamp, not of the window it shines through
