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"

Dynamic parameter has no effect on Beam Particles

Dynamic parameter setup in material does not work with Beam particles. Test material I setup worked fine with regular particles. Could you check if this is a bug?

Can you post your effect to a location one of our QA people can access, I am sending off an email to help verify the issue. I have not had any problems with DynamicParameters and Beams, but I also have not used them in conjunction in a month or two so there might be an issue.

Hi Pinepanda,

Thank you for the feed back. We were able to reproduce your issue here, so the developers will be looking into this.

Thanks, TJ

This is still an issue.

You can use particle color in place of dynamic parameters to modify material parameters as a work around. If you want to scale your color you can setup color as an InstanceParam and say modify it with your R channel, then use another channel such as G or B to modify a separate material parameter.

Sorry for the issue, I would suggest using the above method as I don't see this getting changed in the very near future as we are focusing efforts on Niagara and issues which are critical path for Cascade (i.e. a bug which is causing crashes etc.)

too bad Niagara took another three years eh... Still an issue in 4.19

Hi Everyone -

I want to apologize, this issue fill through the cracks when we were changing over to a new reporting system. I have reported it again, for reference UE-13679 and as soon as I hear something I will report back here to you.

Thank You Clapfoot Matt for bringing this to our attention.

I used the RBGA channels with particle color in Fortified to create similar effects with dynamic parameters as noted in this thread somewhere. It works the same way. There are quirks but you can still create cool effects.
