Spring RTS Engine

Hello there,

I try to export a model from blender to spring. Everytime my texture in spring is black :

I tried with differents formats, differents colors for tex_1 and for tex_2, but everytime I get something wrong. I using blender 2.49b with blender_spring_plugins-0.6.zip

can someone help me?

You've got no alpha channel on texture 1 thus the alpha value defaults to 1 which results in the entire model having team color, assuming that black is your team color.

I wonder if the default could be changed by spring...

ok ok... for gimp Alpha = 0 means transparent and for spring means opaque

thx

these are 24 bit RLE compressed (as in zipped) TGAs, they got no alpha channel

right!
After your first answer I make a texture version with alpha channel, and I saw that 0 means opaque for spring

Well, alpha channel in spring actually represents teamcolor, which helps you identify which team the unit belongs to ingame. For example, the orange in this picture:


full opacity (255, ff, whatever you want to call it) means 100% teamcolor, so a flat color (in your case, flat black).
0% (fully transparent) means no teamcolor, so it's the texture.
Anything in between (semitransparent) causes the testure to be mixed with the teamcolor.

Keep in mind that this is only true in the texture1. In the texture2, the alpha channel has a different effect, and is actually unit transparency, and you can mess some things up and come up with invisible units by making the teture2 transparent.

Hope that helped, and happy modeling!

thx
