How can I give an object with a shader a transparency (gradient) independent from the current shader?

How can I give an object with a shader a transparency (gradient) independent from the current shader?

Thank you

Hello @steilvorlage.de

You can do that by using V-Ray Blend Material. Add your shader to the Base Material slot and a Transparent shader to the Layer 1 Material Slot. Then add a Ramp mask and adjust it to your linking.

Hi Viktor,

thanks for your fast answer. The problem with this method is, that the scaling of both shader is not independent. In my case I wanna have a big disc that is going transparent at the edge (gradient) and the texture of the disc is grass, that is tiled very often.

Thanks
Tobias

@steilvorlage.de , this method allows you to edit the shaders independently, you are simply using the V-Ray Blend material to combine them at the end. Please, refer to the video I have recorded: http://ftp.chaosgroup.com/support/scenes/Cinema\_4D\_2023-10-10\_08-51-27.mp4

If you ask me, this is not flexible. Because of the same projection of both shaders, you have to change the shader itself to have more tiles on the object. Flexibility looks different, sorry

Hello @steilvorlage.de Could you please give us a more detailed example of what exactly you expect as an outcome?

Hi Viktor, I think he needs the base shader to have one projection and the transparency shader to have a different one, so that he can use the transparency gradient independently from the base color.
