After more headbanging (see Illustration No. 1) I figured out that it appears that by setting Source Alpha Blend to zero from the default of one, and setting Operation to Add from the default of Maximum, that it works like the DX9 version - at least with the things I’ve tried so far. I had naively thought the default settings of the new Alpha pins would be equivalent to the DX9 behavior.
Does anyone know of a good example on the web of all the DX11 blend modes? I have not turned up anything really definitive in my searches.
Thanks joreg, that much I can find. But what about the other pins on the DX11 node:
Alpha To Coverage
Operation vs. Alpha Operation
Source Blend vs. Source Alpha Blend
Destination Blend vs. Destination Alpha Blend
How do the Blend operations factor in versus the Alpha Blend operations in the formula? What do the Operation “Maximum” vs. “Minimum” options mean in practice? The greatest/least of source vs. destination?
Being a very visual person, what I would really love to find/make is a chart showing the effects of the various combinations so I could just look up what I would like to accomplish, but I can’t find it anywhere.
