-
using an image in environment slot with spherical mapping and it`s completely garbled. (blocky and weird.)
no difference with filtering change.
no change with `CoronaMapOutput`(although I don`t know if thats what i should be using, sorry ?)
thought I`d post here in case I`m doing something wrong.
It was ok in v3 Alpha.
-
ok, ignore that image.
didn`t save out right.
-
this is what I mean
-
Use Vrayhdri
-
Works fine for me... Tried using different images?
-
it was in a scene i merged in from v3 (converted from vray), the hdr didn`t work so i tried a jpeg and that didn`t work either.
i`ll try in a fresh scene. yes that works fine. hmmm.
-
post the scene (with the image) if it does not go away
-
stripped down scene, just a camera and the bitmap.
it does it with any bitmap and even when using a new bitmap `map` and new selected bitmap.
something screwy in the scene maybe.
Note: I converted a vray scene to v3 then merged to become v4.
I reinstalled v3, merged `just the camera` from the scene and reapplied a new enviro map and it works fine.
I reinstalled v4 again merged `just the camera` from the scene and reapplied a new enviro map and it`s a blocky mess.
Also tested just loading the scene again in v4, same blocky thing.
attached the scene and a map to test.
-
forgot to mention this was in 3dsmax 2012.
so I`ve checked in max 2013 and it`s the same.
-
It is a numerical imprecisions issue due to the way camera is handled in A4. I can't fix it easily, you should move the camera closer to the scene origin. 3dsmax has also problems with the viewport in the unit ranges you are working with
-
good you identified the problem, but why does it work ok in v3 and not v4 ?
-
sorry, you said A4 in the reply above, I was looking for `v4`.
Is there no way to make it more universal though as sometime scenes are like this, especially from outside clients. If you resize/relocate the scene and then they send updates that makes extra work incorporating the new data. Does scene scale affect the noise/sampling/lighting etc ?
-
good you identified the problem, but why does it work ok in v3 and not v4 ?
I've changed the way some camera operations work.
There could be some other effects on the scene (mainly self-intersections). For example do not expect that you would be able to model fine details (this is a restriction on the max level, not Corona)
-
confirmed it works in my scene, move to 0 and rescaled.
that`s autocad exported scenes for you.
