Houdini Lounge » Maya to Houdini Scale issue

Yes, maya units is different. So if you model in maya a real car for example, you can set maya units to centimeters, and work with centimeters as if it was meters So your car should be 3.5 cm in maya, then in houdini you get your model with proper scale. But i find it easily just to scale geometry to 0.1 in houdini….

Yes, of course, houdini have support of multiple UV sets, because UVs - is just a regular vertex/point attribute. You can have as many of them as you want.
There is a layer sop for that
http://www.sidefx.com/docs/houdini12.1/nodes/sop/layer [sidefx.com]
After that you can access particular UV layer in shaders, just by importing parameter with Parameter VOP, or you can use Shading Layer VOP

To make fur work with UV layers, you need to dive into fur shader, and import your uv attributes….

You can also get transformations from alembic transform nodes with python: Node.worldTransform().

I have give many tries for houdini's interface and workflow and i think still that houdini really need second option for workflow and interface too. Some kind of interface and workflow which would have “simple and easy” logic with tag's in the treeview.
I don't know any experienced houdini user, who blame houdini interface and workflow. Yes, it's not ideal, but is the best, compared to other 3d software. I also suggest you to work with houdini a little bit more, before you post your wishes
My wishes:
1) Mantra Alembic Procedural
2) CVEX in Delayed Load Procedural
3) More python!!! (implementation and documentation)
4) Python binding to houdini UI Scripting Language?
5) Middle mouse viewport handle drag (like maya|xsi)
6) VEX Coshaders! More advanced vex (like RSL 2.0)
7) More PBR speed!! Make it best!!

Just save your presets(in gear menu), and then include this files in extra files section of your otl. That's it

Copy Stamping technique to modify shader parameters on the instance points.
As jeff said - It's easily doable with Material SOP, No problem at all.

Hi guys! Could you tell me is it possible to use fast point instancing with delayed load procedural on instantiated object?
It works fine with full point instancing, but not with new point_instance_procedural.Is it limitation or bug?
Ok, i know i can load bgeos right in point_instance_procedural with instancefile attribute, but in this case i need to assign materials somehow ( which is nicely done with delayed load and separate material.ifd file).
Thanks.

Hi. Can somebody share a simple hip file that utilizing vm_geo_ptinstance?
I'm trying to make some custom instancing setup, and want to use cvex, but i cant make it to work with vm_geo_ptinstance. Please help me with example.
Alex.

Hi. Previously, in H11, i could copy-stamp simple boxes on points and set only display flag on it, to preview instances in viewport. In H12, instances, forced to display in ogl, and it makes viewport very very slow. Is there a way to disable OGL instance rendering? I know i can drop a null with display flag, but i want workflow like in H11.Thx.

Hi Edward. From what i've discovered, toNDC (string camera, vector pos) doesn't work in shading context. Why is is there such limitation? Thx for reply.

Hi! I have a question on camera projection technique in surface shader. We can easily project texture from current camera, by transforming P to NDC. But what if we need to project from one camera, and render from different. How to transform P to NDC of “projection camera”?. There is a toNDC vex function in houdini help, with this definition:
vector toNDC(string camera_name, vector point)
But this doesn't work. Compile errors : Can't find signature ….. Was this function removed?
So, am i on the right path? I know, i can project from camera in SOPs, but i need shader based approach. Thx!

Shylon
my cpu is intel 2-due-core-E6750
This is really very very outdated cpu. Don't expect acceptable render times with this 6 years old cpu.
