polygon objects wont reflect in the VP. primitives and the sky object do. whats really cool about the sky is you can rotate it and see in reall time where your reflections are going to be and what they look like

I'm now confused by what the updated viewport is capable of...

When I watched this youtube video a couple of weeks ago, they talk about screen based reflections, and show a polygonal object reflecting on the floor

around the 3'00" mark

can you clarify?

ah yes sorry i forgot about screenspace reflections. yes polygon objects reflect but the effect can break down because its screenspace, it will only work in a few situations, like shown in the video, objects sat on a floor at a certain angle.

I believe it's the same as in Element 3D. The new VP features are still quite compelling, IMO.

So its similar to what the Xenko people are doing:

https://xenko.com/blog/real-time-lo...ctions-preview/

Which in turn seems to be based on this:

https://www.ea.com/frostbite/news/s...ace-reflections

As far as I know, screen-space reflections are limited by the fact that they can only reflect objects that are actually visible on the screen, or "in front of the viewer camera".

So if you were to point a virtual camera in a virtual mirror, the mirror wouldn't be able to reflect anything that is located behind the camera. Hence the term screen-space.

I'm sure that there are ways to do real, physically plausible realtime reflections on GPU that work more accurately.

It might drop your viewing framerate, but wouldn't be a problem if you have time to offline render a sequence of frames.

Imagination's raytrace-accellerating GPUs are already able to do real raytraced reflections in OpenGL ES games in realtime.

Realtime Archviz:

The question is whether Imagination's GPUs - which are currently used for mobile devices only - will come to the desktop anytime soon.

And just for fun, here is Edd Biddulph's QUAKE 2 realtime path-tracing demo:

i will share your concerns with Edd the next time we go for a burger and beer together (we are currently trying to work our way through every burger in frankfurt )

Cinema 4D 19....thats awesome!....is it being used more widely now in the film industry nowadays?.....I've always loved the interface.

I would predict that the new viewport in R19 will lead to increased use in film previsualization - 3D animations, not final quality, that allow filmmakers to plan how big, expensive scenes in Hollywood films and big TV productions are shot.

C4D was used for this way back when the classic film "Gladiator" was made.

The new realtime shaded viewport should make R19 very useful for this kind of previsualization, shot-planning, storyboarding and related work.

The only other 3D app I see pushing this level of realtime visuals is Blender with Eevee, which is also very cool - I tried it for the first time last night. Eevee is in Blender 2.80.

A lot of people in film 3D have been trying to use UnrealEngine, CryEngine and so forth for faster rendering film visuals.

Now C4D and Blender may be able to provide that functionality without needing an actual game engine.

Glenn, Im pretty sure im not the only user who noticed you dont post render times of your AMD pro render stills.

I really hope its because its really fast and you want to surprise us in a good way.

He posted a comparison in the Prorender therad here.

You find several vids on youtube with live demos. See here around 8 min. for example:

That video looks great - wish it was in English tho!

If ProRender gets really popular - i.e. C4D, Max, Maya, Blender users all use it a lot - AMD always have the option to hardware accelerate the renderer.

This would mean that AMD Radeon GPUs get ray tracing, path tracing accelerator circuitry for ProRender built into them, and then ProRender would probably become a real speed demon.

I don't know if AMD have any plans to do this, but GPU firm Imagination Technologies are working towards this - GPU's that hardware accelerate ray tracing.

So it is going to be interesting how far AMD take ProRender. Accelerator circuitry in Radeon cards could give the renderer a 5 times or 10 times or even higher speed boost.
