Holy grail... nice one

It seems I cannot rate you higher than this. Damn the forum software
Congratulations ventilator, this is really one of the greatest contributions ever seen around here.

a small addition:



now it supports multiple lights and the lighting equation takes color and falloff into account. shadows can be enabled or disabled for lights (i always wanted this possibility in wed! it makes using fill lights much easier.).

looks quite promising so far. hopefully no problems i didn't think of will arise. it's a pity nobody started sooner with something like this.

So this is all generated from WED? And it supports static lights? And can be generated from WED?

If this is all true, then you are truly the master. If not, your still the master, lol. That is, until I catch up with you

no, it's not generated from WED. after loading the level the light maps get calculated in the engine.

i use entities (small sphere models - see the white dot above) for setting the lights and they could be placed in WED of course. i didn't find a good way to access the real WED lights per script.

in the engine you can change the light position and settings and let the light map update immediately but i didn't work on a light editor yet.

...
maybe i should start a new thread about the ingame light mapper since it is work in progress and not directly related to the two plugins of this thread.

...Sounds like a good idea

Wow, this sounds great. Probably the best part is that it automatically generates the second uvmap(without having to export 2 models). I'm sure many users would find it extremely useful. Looking forward to purchasing it when done.

Hey Ventilator

I can get your script to work, but when I tried implementing it myself I got an error 'crash in bmap_getcolor'.

Any ideas? Thank you!

does your light map have an alpha channel? bmap_getcolor at the moment only works with 888 format but with alpha channel the format is 8888.

No it doesn't have an alpha channel, I get the 888 error if I give it one, it just bypasses that and gives me the crash error, same mesh works in your demo, I've played around with it all, can't seem to find a solution. Let me know if you have any ideas. Thank you!
