 Hi
There is a shadow for 3D person – but for 2D person there is not – how can we solve?

It shows better when rendered than in Build of course.

But yes there is a perspecitve point where 2D silhouettes do not have a shadow when the angle from the camera relative to the suns angle is such that in combination it results in a very thin shadow that is not seen.

So if you change the angle of the sun slightly or also the camera it should fix things.

Woops, sorry about that, so used to looking at L1 with no lighting or L2 daytime scenes   :+

Yeps, looks like bug. big bug, needs adding by Morten broken feature (or maybe not there in first place).

Seems only 3D people have shadows.

Really odd.

Both Remko and I have both tested this in the same build that you guys are using (2.1 Build 3), and the 3D silhouette people as well as the 2D people - and other objects that use the Billboard material - do cast shadows.

Can you check whether you have converted the shadow map textures from your IES light sources to shadow cache textures by clicking on the 128/256/512 buttons instead of Shadow Cache -> Off?

Lights that use Shadow cache textures will not be updated in Build mode unless you press F8 twice to update them manually. They are however updated automatically at the beginning of every clip if you render a movie, and also if you render an image in Photo mode.

Remko will test this on more PCs with different graphics cards.

Stay tuned for more information.

  Merci Morten  now everything has become known now .
I hope that there will be a PDF reference (Supported by illustrations) to avoid problems -- :-D ;) :D

mmmmmmm

As you can see  from the name of the render file I did, it was rendered by going to video editor first to select a clip to render from (but no actual video render), then to photo to do the render.  Cache was definitely Off.

The thing is the 3D character shadow is rendered not the others.

I have tried replicating, but this time can't get same results, and get shadows for both photo and video with cache Off or on any of the sizes, so  ??? operator ? or some very specific sequence of steps.

Hmm, are the shadows also working in your scene again, Kais?

yes Morten & merci  :-D
but still we need reference (Supported by illustrations) to avoid problems -

Yes, I think you're right, Peter, it must be a combination of specific steps and it probably only happens the first time you render these character types after a fresh start (without pressing F8).

We'll definitely keep an eye on this.

Duh, and duh.  Too many versions on my system me thinks, operator you see, can't run the right version.   ::)   :+

Morten,
I have just gone back to re-check how I managed to get no shadows after rendering.  Have been able to duplicate it but it's not a problem.  Seems for my test I had used V2.0B3 in which I was able to duplicate the problem just now, but in V2.1B2 rendering the same scene is all OK. :), no need to use F8, just renders correctly.

Hey I see we even get format types in the file dropdown, progress is wonderful.

Pheew, good to hear that - thanks for confirming that it works as expected.
