This bit me too. You can also set HOUDINI_CC=/usr/bin/gcc-4.8 if you don't want to change the system level gcc.

This only works for hcustom as it priorities HOUDINI_CC over CXX and CC. If you are using make, you will have to modity $HFS/toolkit/makefiles/Makefile.linux to use gcc-4.8 without changing the system level gcc.

Yes Cameron. Switching to gcc-4.8 fixes the problem.

For those who are facing same issue, follow these steps:

sudo update-alternatives –install /usr/bin/gcc gcc /usr/bin/gcc-4.8 10

sudo update-alternatives –set gcc /usr/bin/gcc-4.8


Thank you Cameron!

Houdini crashes when display flag is set to any custom HDK OP. Issue persists even on sample SOP_Star.

Check “backup” folder inside hip directory if there any backup file .

Windows > Desktop > Reload current Desktop

or

If you override any built-in desktops then delete it from home folder. Then launch Houdini, it will create new one.

Since it's shader preset so it should be inside $HOME/houdiniXX.0/presets/Shop.

Find attached otl.
It prints out any point attribute value from point group.
If you are on Linux, it will open log file in Gedit otherwise will ignore it. You can find log file in hip directory.

$F = hou.frame() #or in short frame()
$PT = hou.pwd().curPoint() #or in short pwd().curpoint()

“Get Attribute” VOP imports given attribute from given file or input.
“Bind” VOP adds attribute.
“Set Attribute” VOP sets attribute value if it already exists.
“Add Attribute” VOP is similar to bind VOP and maps attribute. Mapping is the major difference between bind and addAttribute.

Do you have “Display Texture” turned on under Display Option > Texture?

Is you shader have OpenGL?

Maya reads pack primitive well. There might be problem with your alembic importer in Maya.

Because local variables are not supported everywhere in Houdini. $NPT is not local variable for refine SOP.
Use this expression instead:
npoints(opinputpath(“.”, 0))

Check around 17:00 min where Scott explain how to create custom wind field.

It depends on rank of field.

I hope you got your answer on OdForce.

What about using PolyCap SOP with “*” in group mask field?

Renders to Mplay are temporary. You lost those if mplay is closed. You can save renders from file menu or by right click.

What about using $HOME?
