supertrace.zip ~ 500kb

it's a free plugin with a function called supertrace() which works with static models and can return the texture coordinates (of both uv-sets) of the hit location.

(to try out the example script extract the zip file to the directory with the mesh plugin demo.)



for example it is helpful if you use entities with light maps and want to figure out the light map color somewhere or for painting graffitis, blood splotches,... at certains locations.

this plugin makes it possible to use two uv-sets on your models. since the mdl7 format doesn't support two uv-sets, you will need two versions of your model. one with the first uv-set and one with the second uv-set. with the ent_loadseconduvset() function you can load the uvs of the second model into the second uv-set of the first model.

Greatest contribution/plugin ever. *gives Ventilator 1.2 million kudos*

I already gave him 5 stars ^^

very, very useful!

thanx very much, mercuryus

So, theoretically, would it be possible to generate lightmaps using supertrace() ? Or is supertrace actually the other way around, as in it only returns coords from vec, not coords to vec.

for generating light maps it's the other way around. there you already have the triangle and its uvs. you have to rasterize the triangle and convert each pixel's uv-coordinate to a 3d-coordinate and trace to the light from there. i think that's the easy part. the hard part is the algorithm which automatically creates a good uv-map.

I'm not worried about creating a good UVMap (Yet ), I just want to make a 'lil program for generating lightmaps ingame. I can use the TGA code on the WIKI to save them to TGA files. I've already done this with a terrain for a school project, but terrains are easy

if you already have the uv-map for the light map then it isn't much harder than doing it for terrains (med supports automatic atlas mapping now so this could be used for the uv-map).

i think basically you just need a triangle rasterization algorithm and you have to know how to use barycentric coordinates so you can get the 3d-coordinates of the rasterized pixels. both things aren't too difficult and you can find information about it with google.

you have to use lite-c because with it you have access to the mesh data. i posted an example in the lite-c forum a while ago.

an ingame light mapper would be nice!

I've been avoiding light c, lol..

I should probably start digging into it this weekend...
