ent_mtlset() doesn't work anymore for me. it always crashes. exactly the same project and code worked fine in older engine versions (i think it was 7.50).

what could be the reason for this? for example i simply do

ent_mtlset(my, mat_model, 1);

and it crashes. anyone else with this problem?

This was a bug. It happens when you change a non-existent material. This will be fixed in the next update; until then, only change skin materials when they are defined in MED.

now i have a different problem with ent_mtlset().

in the entity action i have this:


the first time i load the level everything works. the second time i load the level the environment mapping material doesn't work anymore. what could be the reason for this?

Is it a level entity or a view entity? If it's a level entity, are you setting the materials after every level loading?

it's a level entity and the entity action where i assign the materials runs after loading the level.

That should work, then. Can you upload or email that project? I'll have to look into it.

Thanks for the project. The reason of the problem was that effects of model-internal materials were released at level exit. Thus, the material had no effect anymore after loading the level the second time. This will be fixed in the next update. You can work around this with using effect_load() for the chassis material.
