Hi ! i finally found some time to look at the example ! This is indeed a strange bug ! I tried to convert the code from the example to lite-c - there the problem happens too (at least for me!) ! It seems to me that this problem is not isolated to the C# wrapper ! I tried several other things, but it somehow seems that ent_fixnormals always resets to the original state of the terrain ... Does the problem also occur for you in lite-c with this code ? :
(edited) : I just discovered that the code i previously posted, in which I said that i can't reproduce the error, now also produces this error !
I guess this is because i used 8.20.1 when i wasn't able to reproduce the error but now after updating to 8.30.5, the error is always produced....
THUS i think the error somehow smuggled itself into existence between A8.20.1 and A8.30.5 ! That's why I guess this is a engine bug, caused by the new Acknex version !
