Texture Error!...

denizsenturk — Fri, 13 Dec 2013 08:19:51 GMT

Hi,
I have a problem with my cga rule.I changed the location of the file,then i imported the file to CE again.But textures are lost.Only 2 of texture image are shown as facade image.In fact,there are about 150 texture image.What can be the reason?...
Additionally,assume that i changed something in cga file,but i did not save it.Although i did not save it ,the cga file is keeping all of the changes.The other problem is that when i use a cga file in 2 different projects and make some changes in cga file in of one of these projects,the cga file which was used in other project also changes.This is so absurd:) Do you have an idea about that?...

Thanks 🙂

There are lots of Turkish words in this rule file,i don't know how much it can be useful for your help :confused:

Hi,

if textures cannot be found, then either the CGA code to define the texture path is wrong or the textures are not in the right place.

make sure your texture path is correct. maybe use print() to debug the issue. comment out all the code that you don't need.

just work with the very basics you need.

the other issue with 2 CGA files with the same in different projects: that would be a bug. are you absolutely sure you dont' edit the same file just because it remains open when you open a different scene ?

can you provide a very simple reproduction ? that would be very helpful.

lemme know ..
