Next major Houdini release will not support 32bit

Just wanted to give you a heads up that the next major release of Houdini will not support 32 bit platforms.

32 bit versions of Houdini are only used by a minority of our customers at this point. Most customers in production are using 64bit windows or linux and given this reasonable heads up (a good number of months away), the remainder will be able to transition to 64bit as well.

32 bit is still widely used on Windows especially for home users.

Linux for sure 64bit.

If the time saved by abandoning 32bit is used to speed up development of the x64 version ->

.. and what could you do in Houdini with max 2.5 Gig ram per process in win32 ? I often struggle with 64 Gig of ram ..

I'm not arguing that 32bit is better, just that removing support (which I have to assume is almost all automated compiling) reduces the number of still-valid machines (laptops in particular) that can run Houdini. Hence, reducing the user base.

Autodesk still support 32bit XP and Win 7. SESI are known for supporting _more_ platforms, not less

Ever since Vista, consistent large memory allocations on Windows in 32b mode have sporadically failed. By large, I'm not talking about GB's - allocating and freeing blocks of around 100MB, which is common when dealing with large models or large voxel sims, will often result in Windows falling over in short order.

This creates support issues, and generally doesn't make Houdini look very good. If only it were a matter of “just a build machine”, we'd happily continue supporting it.

OK fair enough, just checking

I've just recently needed to use the win32 build, just to get an obscure 32bit-only .dll to work with it..

I'm fine with them moving on though, 32bit is close to dead, and will be even closer when the next version ships.

Houdini is “mainly” but not entierly for FX TDs , in my case ram limitation doesnt work, I cannot make miracles with 3gb of ram, What kind of a container resolution with 3GB can make it to the big screen.

Good decision, divert those hours you were spending on 32 bit to speed up the cloth solver.

i think most of the fx users, have the apprentice version on their computers, as well students, not sure how many of them are in a 32 or 64 system.

I can only image, how much this decision simplifies development of Houdini! Hundreds of headache less, hundreds of hours more for cool stuff. Not to mention Adsk has just dropped 32bit support in its suite.
