How to render the inside of an object when using an alpha mask?

Hey Guys,

I edited the new PBR-shader so that I can set the alpha of an object with a texture. but sadly the backside of the object does not get rendered this way. maybe I did something wrong in the shader?

I attached the files. (created with RC9)

thanks for your help :)

sorry, its not allowed for me to upload files to the forum yet, so here is the link

without checking the shader code, just from what i remember, the PBR shader sets alpha to 1 in some places. did you follow the path of the alpha value thru all calculations and made sure it’s not overwritten?

yep, I totally ignore the global alpha. in the pixelshader I return the new calculated alpha value

@qbic the problem is Depth Prepass
i think you need to tell depth that you expect to have holes in it ';]


does it work for you even if you rotate the camera? the objects oclude each other…
