Weird Transparency When Rendering In Cycles Blender Stack Exchange This is my first time rendering in cycles since i just figured out how much nicer it looks with normal lighting, but i'm getting a weird transparency effect on the objects when the scene is rendered with cycles specifically. The gpu and cpu cycles modes have slightly different codebases. a gpu and a cpu have entirely different architecture, and they can have entirely different bugs for that reason.
Weird Transparency When Rendering In Cycles Blender Stack Exchange For some reason they show up transparent in cycles, while being normal in material view. i also have almost exactly the same objects with same material that dont have that issue. Increase the transparent bounces to get rid of black artifacts when using transparency in cycles. long format blender tutorials on our main channel:. For basic materials in cycles transparency can be controlled by changing the colour of color vector of the transparent bsdf which changes the transparency of the image mapped to the image texture node, and or the alpha vector of principled bsdf which changes the materials overall transparency. The object has large numbers of transparent planes, and i raised the value of transparency max bounces to 80, which erased most of the ugly shadows. but there were still some dark shadows on the hair, raising the bounces to 1024 still could not erase them.

Because alpha transparency is shown in black in cycles when you're in material preview, it's only transparent in rendered view. if this is rendered view then you maybe have to go to render settings > light paths > max bounces and set a higher value for transparency (or even for transmission). This is caused by the obsolete blender viewport engine. the alpha faces should be depth sorted which does not happen and it's a known limitation. Observed this effect in blender 4.1, not sure if other versions behave differently. also, to my surprise it doesn't always work this way and things change depending on scale of the object and its topology. But if you render it, the teddy bear is strangely transparent. and the icing flakes are not getting rendered. you still can see a bit brown, but almost all of it is transparent, although the transparency is set to 0 and the icing flakes completely disappeared.
