How to render semi transparent texture texture?

Post by Lukesmith123 » 03 Nov 2013, 23:50

I have created a material with a texture that is semi transparent. It is a photoshop PSD and there are sections that are transparent and I also tried putting an alpha map in the alpha channel.

In my material properties I set Transparency enabled, and I also tried setting Use Alpha but neither worked.

Is there another step that I'm missing?

Stop using PSD with Softimage, try a TIFF instead.

Although PSD is not optimal, it should render.

A basic tree would be, connecting your Image clip to your shader transparency, and in the shaders options activate Transparency, and check on Use Alpha.
You will obviously need UVs on your object.

By default, SI uses white as the transparent part, so you may want to check on Invert too.

Use a sprite node if you are trying to render transparencies. Save your PSD as a TIF with alpha channel. Plug texture into the input of the Sprite. Grab a 'picker' and connect that between the image out and the matte of the Sprite. In the Sprite, enable the matte checkbox and set the Stencil mode to Maximum RGB.

If you want the transparency to display in OGL, grab a mixer with a phong connected into layer 1 and turn that layer off. run the same picker into the transparency of the phong. Check 'use alpha' and 'invert' on the transparency tab.

Hope this helps.
