Corona for Cinema 4D Beta 1 daily build

[houska]

If i use corona_bitmap shader in light material the bitmap is upside down. Why?

It's because of different coordinate systems used for UVW mapping in Cinema and Corona

That said, it is a bug, so we should fix it :-)

Render engine faster than A6.3.

Yes, it is faster the new beta!  :D

is triplanar implemented ?

Synolog HDRI technique with Projector work well. (Hdri using c4d projector shader in emission light material)

- If u rotate the sky object with ligth material, the hdri dont rotate.
To rotate the hdri u need to use projector, rotate settings.

about the Direct visibility override,
for spherical projection :
Material with texture in diffuse ->grey / attachement 1
Material with corona_bitmap in diffuse -> bitmap is upside down / attachement 2
Material with projector in diffuse -> it's ok / attachement 3

For frontal projection :
Material with texture in diffuse ->grey / attachement 4
Material with corona_bitmap in diffuse -> red color  / attachement 5
Material with projector/frontal in diffuse -> purple color / attachement 6

Background is a uv grid cheker for my test.

so, I can't plug a bitmap in frontal projection for my background ..

Thanks CBAS. In attachement 3 the bitmap seems upside down: maybe you have uploaded the wrong image.
Try to use two different lightmaterial with the same projector/hdri in scene override and visibility override: increasing scene emission i can't see the visibility.

put the HDR in a projector does not seem the right way, we expect the updated version.

[synolog]

Why? I dont think so

U're right. i've upload the wrong jpg.

the projector is used to scale the maps and change its position. The HDR should be put into a simple bitmap channel or filter to change the intensity and color. If you want to rotate the HDR, you can do so by turning the sky object.
This is the method that is used in all programs.
We expect the updated beta and will be just as it has always been

In max you use environment map (c4d scene environment) and control the mapping parameters with the environment texture map (c4d projector shader). In max you don't use a sky object with a bitmap. Is it correct? How to rotate the hdri with the sun then?

Thanks. Why is the image inverted?

simply rotate the sky object.

[fabio81]

the image is inverted because there is a bug. We expect the new beta and solve problems :)

[synolog]

Thanks

Grrr, Still getting a crash sorry to say. Bug report attached.

Don't say sorry it is daily build it can crash but we will fix if of course.
