Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

I want to change a mesh material with a button

Hi everyone, I'm trying to change a mesh material by clicking on a button. So I have three buttons on a HUD that are setting an index number for a material array when clicked, although it changes the material, it only shows me the default squared material. I've tried to plug a simple variable containing a material in the set material, but I've had no better results . I'm trying to make it work for mobile. it works fine with the shader model 5.So i'm beginning to think the set material is not optimised for mobile ? Here is the object's blueprint. Every comments would be most welcome. Thank !!

Here is a little update. The set Material works fine with a static mesh when the lighting is not build, but as soosn as lightmaps are applied, the default material is applied, so I guess I shoul have to find a bit more complex way to assign my new material fot it to keep the lightmaps and the reflections... All help will be welcome !!

Cheers
