Hey all,

I'm trying to set the environment variable HOUDINI_USER_PREF_DIR - to a specific folder.

I have other environment variables working perfectly, but I cannot get this one to work regardless of whether I use a windows environment variable or place this inside the Houdini.env,

Everytime I open Houdini and check the shell using hconfig, it says my temp directory is set to the default directory,

does anyone have any ideas? My only guess is this is being set elsewhere and their fore overriding my manually created env varaibles.

(Ive checked spelling etc. and this is what my windows env variable looks like; name = ‘HOUDINI_USER_PREF_DIR’, value = ‘D:\Houdiniprefs’ )

Thanks
Chris.

Hey all,

so I'm working using the gamedev toolset, and made sure to update using the button inside Houdini.

I'm finding my flowmaps to be quite strange, If I put down a create flowmap node, set the values to 0 so no flow. Then convert to colour and export to unreal, I get constant movement in what looks like two equal axis/direction, but surely the flow should be 0 and theirfore 0 movement,

Looking into the tool it seems both x/y in Houdini are always set to the value of 0.5 when converting into a colour which I don't understand why,

If anyone could explain what reason this happens or why, or if this is actually a problem anyone else has faced?

On all tutorials Ive watched they don't seem to have any issues

Thanks
Chris

So a small update;

Soft Body for cloth etc. - all working well (theirs a guy on the odforce forum saying he also used the soft body method for a small fluid simulation which worked with some tweaking)

Sprites - all working (need to turn two sided on in the UE4 shader for visibility - but possibly a normal issue so flipping normal in Houdini before export may work too)

RBD - Working but not properly strange rotation interpolations etc (but possibly a small error on my side may fix this or the rotation calculations within the shader may need some tweaks?)

Fluid - Sometimes works kind of (movement is roughly their but horrendous holes and glitching throughout the mesh - as I was writing this tried to export again and this time it doesn't work at all inside UE4 which is odd)

(PS; I have tried various settings and iterations for these methods not just erroring and not making a second attempt - but if anyone notices me making silly or simple mistakes or has solutions please let me know! )
