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"

Material editor crash.

I am experiencing a rocket crash while using the material editor when attempting to delete an old custom material function after adding a LandscapeLayerBlend expression AND adding 2 layers. I expect that deleting any node might cause this, but at the time, my very basic starter material only contained custom functions. I can successfully delete the LLB expression and not crash the client.

If I delete the LLB node, I can delete the other custom functions without crashing my client as well. I've included screenies of my work pre and post crash.

If I don't add the two new layers, I can delete my old functions and not crash the client.

So quick order of operations for me was: Add new landscapelayerblend expression, add two layers to the LLB, attempt delete of custom function.

Also, attempting to save the material after adding the LLB causes the client to crash.

Hello,

There is a known issue with the use of the LandscapeLayerBlend node which causes a crash. This issue has already been fixed internally and is not expected to occur in the next Rocket release.

Thanks! Glad to hear it.

Do we have a sense of when the next update will be?

We have a big demo coming up in the second week of March so we're hoping we can get the fix well before then.

We do not expect to have an updated release prior to the GDC in March.

There is a workaround you may wish to consider where you can run the Rocket editor with the old version of the Material Editor. To do this, launch the RocketEditor.exe with the command line argument -oldme. The LandscapeLayerBlend node does not crash in this case.

Cheers
