Dark lumps inside the transparent objects

hi so i got a problem here with transparency, made a big mess in the nodes trying to get this kind of transmission roughness without the principled bsdf, cause if i add it i have to figure out how to do the base color and bumps from the beginning, and i like the structure as it is now. it is transparent the object but its not visible in the render, i cant see the backface of it even though ive put the transluscent bsdf. do u have an idea how i can make this milky transparent rubber meterial where i can see the back face of it…?

(im a begginner in blender still just figuring out the ways here…

hi,

it is hard to tell what may be your actual problem. If you wish, you can drop your blend file and I’ll take a look at it

sorry computer got stuck a little, when it starts computing again ill drop the photo of nodes and the photo of other material i made which has this backside of object visible when transparent.

I wanted to play with your nodes as well in order to get that effect you want to achieve. You can drop a photo, but I’m not sure whether I could help you or not in that way.

ok. i just dont know if im allowed to share it, the form is not mine. i send maybe just the material on a sphere is that ok?

In that case show your nodes only, maybe I could help you, but I’m not sure. Maybe you need to reduce your roughness somewhere in order to get glass effect.

Change Glossy on the Glass node instead.

What’s your Blender version?

version 3.6

Correct if I’m wrong but I see that your object appears transparent, or it isn’t what you’re after for?

it is transparent, but i cant see the backface of it as in here - its some other try of the materal i had but dont like the structure

ok. maybe i got it maybe its just the matter of posistioning…

Here you go, hope it helped you somehow
