There shouldn't be n-gons in your geometry, why? Large flat surfaces (100% flat) can either be an n-gon, or hundreds of polygons. In a scene, if multiplied by the number of surfaces, by the number of models it saves on polygon count to have n-gons. What's the problem with n-gons?

In a PBR material there is a height/displacement map., but some materials only come with a normal. Do I use the normal as displacement under "Enable Texture Displacement" of the Principled Shader of Mantra? or do I need to generate a height map for this field?

I came across this, I hope it helps:

I'm having trouble using the colour attribute in translate of a polyextrude, I've seen $CR being used, is it phased out as part of moving from hscript to vex? If I want to multiple the translate value with value, what's the new way?

It really doesn't want to work for me, it's completely ignoring the curve. Here is the file and the making of the file (video recorded less than 2 minutes). Any idea why it's not working? Polyextrude_Along_Curve-1.m4v untitled.hiplc

I can't get any geometry to extrude along a curve, here is a screenprint for a box, which was illustrated in a 2015 video by Sidefx. I have tried polygon curve, nurbs curve. Has something changed? am I doing something wrong?

I have made a model, added a material. Then from that model down the tree of nodes I made another model, still inheriting the "1 prim attribute: shop_materialpath". When I rendered the 2 models, only the first one has the material assigned, the second not. Why do I loose the material when I create a 2nd model from the 1st that has already a material

Found it and it's also 2 clicks in Houdini:

Is there a quick way to show UV overlaps if there are any? I have seen there is a very handy [select->select overlap] in the UV view of Blender, but when I searched for Houdini I found this video: which is quite a lot of steps for something that is 2 clicks in Blender. Is there a faster way that works also for UDIMs?

For Studios, stability is a priority, upgrades between productions only happen if justified, at least this is the case for Autodesk software where the gap can be several years. I was wondering how far are you / your studio behind in terms of Houdini version?

I read in SideFX docs: https://www.sidefx.com/docs/houdini/io/ocio.html "Renders from Mantra are in linear space." So no ACES in the rendered EXRs?

I get visible seams between the trunk and the branches, and between the branches and sub-branches. There is a Enable UV blending option which gives some black and red colours that apeear to be useful for blending but I don't know how to use them. Any idea?

I'm in stage (Solaris) context. I have added a test geometry rubbertoy, a domelight, and that's it. Now I want to export as USD, I use a USD rop, I save the file. and open t in Pixar's usdview. The rubbertoy is there, but the material doesn't show up although it's listed in the treeview. I've tested with the tree usd scenes from Pixar (Kitchen set, city, usdskel) and it looks fine, all the materials are there. What am I doing wrong for the rubbertoy material? (the order of attached images is inversed)

Is there a way of importing an attribute from the geo world to the heightfield world? I want to use the mask generated by the new node in 18.5 "Distance from geometry" as a mask in the heighfield. I've tried Bind import in Heightfield VOP but didn't know how to connect it? I can bring attributes from heightfield to geo but not the other way around. Any idea?

I have a point cloud, only one is the lucky winner, chosen randomly to get a geometry copied to it. I've seen rand(@ptnum), not sure how and where to use it.
