As I know Flux asset affects the desire to try Houdini(especially Indie version) for some people.
In that topic I posted links to videos with new features.

We've noticed you bumping your own thread to promote your modelling tool

I think some of the people who bought houdini indie to try flux still want to read that topic


For me, very personally, it's somehow ‘too much serious’ tool for app I'm using only for experimental purposes. While for majority of users, I'd believe the main output is ‘beauty of code’, not any real result like soft boolean.
In other words, if you'll be able to create a plugin for Maya or Max ( so, not one based on Houdini Engine or anything Houdini related), I'm pretty sure, your work will be valued a way better.

Yea, thanks. I'm hoping the info in this thread will pile up, because I don't, by any means, live under the impression that what I did here is a comprehensive analysis on what goes into Mantra's dealing with geometry generation at render time, either from an optimization pov or a looks one. In order to get there, this thread will have to wait for me to become a Mantra expert or to have other users chip in with their knowledge and practical results.
I know the user base in general is not focused on this type of work, but I'm sure there a few out there and I'm hoping they'll take notice and respond.

Imho, generally you'll want to use render time subdivision, and better dicing quality if first option is not enough (both are under parameters of your geometry). That's, well, generally. Mantra seems to be using a sort of Renderman style, render time tessellation, so if mesh is not tessellated enough, it can't place the texture. That's how for example 3delight is working, but, while with 3delight plugin for Softimage, two or three parameters are enough for pleasant life (together with built-in automatic texture conversion), and error is just a blurred image - in Mantra, there are much more parameters able to do something wrong, object local and global render options. For example I'm not sure is there a way to get MIP mapping from external tifs, or there's always necessary to manually convert to RAT.

Not an answer, anyway somehow I got a habit to avoid any bitmap input in H, except environment texture. Good luck.

Hi,
something like this maybe?
Nah, this is closer, but H has some strange behavior to add the ‘refinement’ over existing surace, not to rebuild it from scratch. You see it when converting to mesh. Theoretically it's nurbs chord length reparametrization that should work (that's Basis SOP in H), but somehow in 3d apps this makes uniform distribution only for textures, UV and so on, not for possible conversion/tessellation into mesh. Btw, even distribution in Maya belongs to conversion/tessellation into mesh, it's not ‘pure’ nurbs functionality. While H Convert SOP doesn't seem to have such, ‘even’ option. Anyway shouldn't be a big deal to build HDA from Carve-Resample method.
