Hi!
I've got a problem when rendering points as sprites.
I've got a lot of points scattered from grid.
In the objects->Render->Geometry tab I've set “Procedural Shader” to “/shop/vm_geo_Sprite1” shader, which is of type: “Mantra Sprite Procedural”.

to these points I've added 3 attributes: spriterot spritescale and spriteshop
spriterot spritescale - they both are working - are rotating andscaling the sprites, but, when I'm rendering the scene - these sprites are white, and
attribute spriteshop is set to String: “/shop/v_layered1”, where v_layered1 is material with Mandril.pic.

How to render them with this texture? Am I making something wrong?

I found partial answer - everything work good, when I create material with my “VOP VEX SURFACE SOP” connected to “Surface Shader” and my “Mantra Sprite Procedural” connected to “Geometry Shader”
- then, after aplying this material I can see sprites with texture!

But Is there any method to make this effect without assigning this material to object?
only with (as I said before) setting:
the objects->Render->Geometry tab-> “Procedural Shader” to “/shop/vm_geo_Sprite1” shader, which is of type: “Mantra Sprite Procedural”?

just include spriteshop in attribute list on sprite procedural

or

you can directly use your shader in object material slot and keep your procedural on object as well (not as a part of material)

Hi Danilo,

I saw your last scene, and I think you have just forgotten to put /shop/v_layered1 in the material tab of your geo1 object.


Cheers,

i think i made mistake in my previous post

the method 1 should be:

create point attribute “shop_vm_surface” with the string value “/shop/v_layered1” and also include “shop_vm_surface” in attributes of the sprite procedural shader
with this method you do not need anything in material slot of the object
(“spriteshop” seems to be only for viewports)

the method 2 is obviously working fine and i use it preferably. Use method 1 only when you need control over surface shader per particle
