This is my experimental render system without post processing procedures. Whole surface process is done by LW Nodes system.
Here are pro and con aspects which I got from this interesting experiment
Pro:
- fast response for updates – immediately after render we see our tweaks with surfaces
- easy surface update – based on curves, mixers and SimpleColourCorrector
- more realism in render – post processing is not necessary after rendering so image is not destructed by our “idea” of post processing. Post process can be also gently added (for example bloom effect, motion blur, little curve correction)
- QMC sampling based on Photon Mapping solution which gives similar accuracy of Path Tracing but a couple times faster better speed
- pure physical behavior based on real reflection, albedo diffuse system and no specular system (this is my idea for simulation in renders)
Con:
- good knowledge about Nodes especially with surface mixing
- problem with general light – system force users to create immediately in the beginning good light solution which is very difficult in K2…but I think everywhere (situation will change in K3)
- needs more preview renders then standard amount (situation will change in K3 when KrayVPR will allow user do it in real time)
The bloom effect is done in Kray by command:
Code: Select all
post process gblur,5,0.4;
5 is strength of blur
0.4 strength of effect (40%). This is based on blending between normal and blurred image. Parameter 0.0 means no effect.
Differences between Kray RAW render and photo reference comes from no data about real lights in scene (special stand lamp for photographers – I think this reddish color on the sofa is from that lamp, Sun direction and also dimensions)
What do you think?
