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"

SetTextureParameterValue node is not working anymore

SetTextureParameterValue node for changing the texture of a material instance from the blueprint is completely broken. I can't change the texture of the instanced material from the blueprint anymore. This was working on 4.10.

Hi SumFX,

Can you show me your material setup as well as your blueprint setup for how you are setting the dynamic material instance as well as how you are altering it?

Hi Adam, Sure;

All other type of altering are working by the way (Vector, Scalar). As i said, exact same setup was working before updating from 4.10.

Hi Adam,

Any luck for helping me out? Or we are sure that it's a bug? Thanks.

Hi SumFX,

Unfortunately I have not been able to reproduce this on my end. Do you have an example project that I can take a look at?

Please keep in mind that we ask for at least 4 days before bumping a thread. This gives us time to look into an error and attempt to reproduce it on our end and keeps the answerhub clear so we can parse through information.

Hi Adam,

I've created a tiny version of my project. Here's the link: http://sumfx.net/ue/b53/TextureSetProblem.rar

  1. Open "Test" Map.

  2. Change the values of the actor named "Chameleon" which is the problematic one. (As you can see the scalar values are changing normally but the Texture slot has no effect)

  3. All of the blueprint functionality is in the function named "InitChameleon"

Thanks for your time.

Edit my previous comment: MID actually works without a problem at least in 4.12.5.
