RHEL/CentoOS and Houdini support Oct. 15, 2018, 2:46 p.m.

The 2018 VFX Reference Platform [www.vfxplatform.com] requires GCC 6.3.1 with C++14 enabled when compiling C++ plugins on Linux, so other 3D software packages will require it this year also. GCC 4.8.x doesn't support C++14, so some things would probably not compile. I don't know whether there would be any issues if you're not compiling C++ plugins, (though I'm not an expert on Linux library dependencies and such).

how to select a primitive from detail class with VEXpression ? please help Oct. 12, 2018, 11:58 a.m.

VEXpression: @Area == detail(“../attribpromote1”, “maxArea”, 0)
Attribute names are case sensitive. Also, a couple useful tips are that the detail VEX function [www.sidefx.com] doesn't need the 3rd parameter, since it's just ignored anyway, and most geometry reading functions will accept integers to refer to input geometry, so you could do:

@area == detail(0, "maxArea")

Hopefully that works for you!

Edit: Oh, also, the other big thing to note is that if multiple primitives have the same area and they have the maximum area, it might select multiple, but that might be fine for the case you need it for.

HOUDINI 17 installation failed, help! Oct. 12, 2018, 11:45 a.m.

Houdini 17 doesn't support AMD's CPU?
Modern AMD CPUs have had SSE4.1 for about the last 6 years. It's unfortunate that you seem to have one of the old ones that only supports SSE4a. Sorry.
