Creating a material with open space

[Kimberly Rodgers]

In accurender you had the option of creating a material that could have cut outs in it.  You would upload the image, select the "white or black area" hit delete.  Then when you created the material light could pass through.  For example I created a punctured metal ceiling

how do you do this with accurender nxt

It's pretty much the same. Use the Advanced Material Editor-- the Texture Tab lets you bring in your texture (image)-- the Mask tab controls masking-- the Transparent Checkbox makes the mask transparent. By default, nXt is now set to use Alpha Channel masking since this is now more common-- but you can switch to color masking if you like.

Normally I would select the color that I would want to be transparent.

Say I have a material that is mesh, how do I set it up so everything but the mesh is transparent. I set the mask to transparent but the background is still there so I do no think I did it right

[Roy Hirshkowitz]

Click on the color swatch to pick a color for your masked color. I don't have an eyedropper tool anymore-- if you need finer control than this your best bet is to use an image editor to create an alpha channel.

Use these to start if you are still having problems.
