[Opensim-dev] UpdateTexture or UpdateTextureEntry - OpenSim 0.7

[Gajananan Kugamoorthy]

Hello

Thank you for your reply.

Please see the attached images , I am using some external data to create prims 
in the world . When I use the color information in 1 -255 range e.g. <142, 255, 
142> (with the color light blue I see in the external data) from external data 
and  use that color information  to create a prim  in the world,  I get the  
light green prim. There are more example like (yellow is seen as pink). In my 
case, maintaining the color information is vital.

I thought , there should not be any changes in the color format. I agree that 
middle one is strongest. But what I dont get is that why there is a change in 
color. 


Best
Gajan

This works as designed. The middle (green!) component is strongest,
so the prim WILL be light green. Why you would expect light blue is
beyond me.
