What is about to make a support for additive translucency rendering style? I mean the system that makes sprite parts as more translucent as their gamma less bright.. (for example absolutely black parts on sprite = absolutely translucent and white parts absolutely visible.. etc..) That will be usefull for creating more optimised hires effects for plasma,explosions and so on.. <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" /><!-- s:) -->

Sounds good, but I think it would be difficult to add to the direct3d and opengl renderer IMO, Janis should know for sure, but I agree in that it would be cool for nice effects on sprites <!-- s:) --><img src="{SMILIES_PATH}/icon_smile.gif" alt=":)" title="Smile" /><!-- s:) -->.

Does vavoom support PNG format for sprites? If so, there is no need for this type of thing, as PNG has an alpha channel. You can easily create an alpha mask from a color, for example to get the effect you are talking about Gimp users can use the "Color to alpha" tool and select black. So, does anyone know whether we support PNG sprites?

[quote="spiderman":3187ycvf]So, does anyone know whether we support PNG sprites? Vavoom support PNG format in textures, graphics, and 3D model skins. So i think that it could be support PNG sprites without problem. But it's better to wait for an official response from our Vavoom's dad <!-- s8) --><img src="{SMILIES_PATH}/icon_cool.gif" alt="8)" title="Cool" /><!-- s8) -->

Additive translucency is a planed feature, some of the ZDoom special effects use it and to make them work I'll need it.

No, it's trivial to do it there, it's software renderer that needs special handling.

Does vavoom support PNG format for sprites?

Yes. To add offsets you'll have to use a special utility that you can find on ZDoom site.

Thank's a lot Janis, i'm just creating high quality sprites for different effects from doom, hexen and heretic, they need this feature =) offtop: i didn't forget about new models and effects for vavoom, i only haven't much time for that now =( But i'm working.. =)

Implemented.
