hello all
I'm projecting pictures with camera projection (uvtexture : Perspective from Camera) on a model and rerendering it from a different point of view.
I'm having two issues atm
1/my model is relatively low def and there's a lot of “warping”.
to resolve this I cranked up the resolution of the mesh with a remesh node before generating the uv .but it gets very heavy.
Back in the days , with softimageXSI , you could define your texture projection as implicit or explicit.
I guess explicit means that the projection was done by the shader at render time.(?)
is there a way in Houdini to have this behavior?
2/the resulting renders with default parameters (micropolygon , 3x3 samples , gaussian -w 2 , ray variance antialiasing)
are not as sharp as the initial pictures.I tried a lot of different combination to try to match initial sharpness but It's somehow confusing to me.
what would be the best approach/settings to get the final render as close as possible to the initial picture (in terms of sharpness/details) …
thanks in advance.

hello
I have a cloth object with sbdpinconstraint.
I'm trying to animate the group of constrained points to release gradually the pinned points.
the sbdpinconstraint has the cloth object as constrained object
and a group of points as Constrained points that I'm animating on the initial cloth sop.
so far , no success , the group doesn't update during the simulation.
globally I'm trying to achieve this effect (see #5 movie)

I've tried that

idem no success
I've also tried to animate a pintoanimation attribute across my points but no luck also.
any hints would be welcome !
thanks in advance
