Displacement bug in alpha 5 RC1

[Chakib]

Hi guys,

I was testing the new Apha 5 RC1 ( thanks to keymaster ) legacy build, and i've found this bug :

Displacement doesn't work good in Alpha 5 rc1.

Here is a test with Alpha 4 :




and here is the  Alpha 5 result :




The Displacement map  is combined with a simple Color Correction map.

And if you try without a color correction map?

Can you upload me the scene?

Indeed, the displacement does not work!

Yes, at all does not work displace map in material, corona does not see map.
Such situation both with usual bitmap and with coronaNormal.

Yes, i was doing my Pacman candy scene (wip gallery) and i was using displacement and V4, no problems, then i switched to V5 RC1 and the render seems strange... I had to use displace modifier and remodel part of my model to use it, and drop from using the displacement on shader. :(

Result: if to take a scene in which already was displace map in material, and render in A5rc1,
That is simple not correct display displacement.
But if to create a new scene at once in A5rc1 displacement it is not displayed absolutely, an absolute zero.

I should have the displacement problem fixed, try the new assert in _2013 folder

[Tom Zamorin]

no for me

[Ondra]

Can you send the scene?

[Tom Zamorin]

Ondřej, see e-mail.

[Ondra]

Ondřej, see e-mail.

There is one global switch to disable/enable displacement in the common render settings dialog (under resolution etc.). You had it unchecked, hence all displacement was disabled.

[Tom Zamorin]

AHAHA! Ondra has reduced all from mind release A5)))

ps. Polymax, now you are glad??? :)

work fine, thanks Ondra!

Hi everyone,i know this isnt the topic to talk about but i like to know if in this release of alpha v5 will come a new option of keep continuity on displacement map like in vray or near in the future?, since im having some problems with displacement corona v4 i attached a pic of the settings i use and the map. thanks a lot keymaster for such a wonderful render engine.
