v19.5a real time alpha-channel render glitch

[R Reynolds]

Here is a comparison of a real time screen render of the same model. v19.5a appears to have an issue with alpha channels in decals, rendering the patches as clear. Progressive renders are correct in both versions.

Yeah, this has been a problem for alpha channels in sprites too.

If you can present a sample PRJ for this... it will save me from having to do it

Sorry, Robert, I just saw this now. I'll get on it.

Use v19.5a to open the attached embedded project of the jungle queen's head which has been decaled with text with an alpha channel. The image on the left shows a real time render of the head. Progressive renders produce the more correct image on the right.

I noticed this issue was present with version 19.5E when trying to view decals with an alpha channel in the viewport real time render (renders correctly though in the render preview and final render mode) but I haven't tried 19.5F (latest release as of writing this) so I am unsure if it's still present.

I recall looking at this long ago and noticing it has no decal to go with the PRJ but forgot to bug you about it.

Here is the current appearance in v19.5f of real-time and progressive renders of Rodger's PRJ if I make my own decal to replace the missing decal.

I believe the missing bit of the "T" is because that patch that is on never had any visible pixels on it with the original decal.
