LDD2PovRay Speed Rendering Trick

[raptorscream]

wouldn't rendering with 'Don't bevel transparent parts' be the same as this whole method?

[___]

@bbqqq please cannyou tell me with what settings did you achieve those nice clear transparent parts without any side artefacts?

Cos whenever I do render in POVRay using LDD2Povray and nevermind what my settings are I always get grainy edges on transparent bricks...

@raptorscream, In most case this trick still faster than'Don't bevel transparent parts' because to reflect/see-through "bevel non-trans parts" on transparent parts takes long time to render.

@bublible, For 'Don't bevel transparent parts' : use AA.

For speed Trans trick: Don't use AA but render in 200% resolution (to make sharp edge mask). So you can scale down to 50% after combined images.

And, please, can you tell what exact values of AA you set in LDD2POVRAY (...or I guess we are talking about it here? Cos I am building in LDD)?

@bublible: No special value, just defult settings. In Rendering tab, check the check box "POV-Ray anti-aliasing parameters" Method 1 (good).

Well, when I did that before I had some strange side artefacts on bricks (part of bricks glued together, others have like torn/partly missing edges etc.) and when do not use AA at all the image is simply so ugly that is has no use.

See, just for clarification: I am not using your technique, just being cought by super quality of your renders specialy trans parts (glases).

In fact I am trying to achieve some compromise solution to render all at once, having six-core CPU it is not that bad, so my actual settings (being rendered as we speak) seems to solve most of the problems I had:

- trans parts have no more grainy edges

- there is no visible gluing of brick parts

- I TOOK ONE OF YOUR TRICKS rendering in 2x resolution I need and then scaling it down...seems really do the magic on the trans bricks edges, thanx

- having continuous base plane to background gradient with displayed kind of planet's glowing rim and stars all rendered at once in PovRay so no additional editing/composing needed ;)

Basically still tuning some details but main work is done...let's say 90% - I just need to write script for the pseudo base plane to be facing camera at the same distance and angle with every render of MOC I do independently of actual camera position and angle.

...and this is my result (yet still with the need of manual readjustment of the baseplate for every MOC, but being working on the automation at the moment...):

This method is brilliant and has saved me *tons* of time, so thank you! Especially to bbqqq & KielDaMan!

Please modify your LDD lxf file to additional two versions before render. ???nt.lxf = no trans part. ???bw.lxf = trans part white color, others black color.

Is there instructions on how to modify the lxf file?

Hi, I'm sorry to dig this topic up, but after trying all the suggestions I still keep having these white artifacts on my trans bricks.

I did:

1st pass: B&W (original LDD geometry, no baseplane, no lights, no radiosity, no material, quick colors)

2nd pass: Original with everything (original LDD geometry)

3d pass: no transparency (all bevels)

I tried with double the resolution (2304x1440) and even quadruple (4608x2880) and no AA, but the result is still the same: white artifacts...

Does anyone know a solution for this?

Edit: I should note that I render in Windows via a virtual machine (Parallels) within Mac.

You just have to duplicate the .lxf-files and then rename them so you have three different files to process.

Can someone please explain all this in layman's terms? Can you make a step-by-step guide to doing this?
