Quick rendering using Vray Sketchup/ Vray SR

I am writing some tips here using Vray sketchup

If you want fast rendering time.

1. Do not use QMC. QMC calculation is the most exact yet the slowest.

2. When using IR engine (say-5, -3) calculate faster but be aware of light leaks. for final render you can make it higher

3. Use Light Catche as your 2nd engine. the Default 1000/ samples .02 size/ make it 500 or lower . Be sure you tick the glossy box something.

4. Now its always advisable to save your IR and LC and reload them later. so if you rerender again your image, vray wont calculate those things anymore and it will go direct to rendering process. Also saves on the memory used in the final render process...very advised for HiRes

5. Image Sampler... Adaptive Subdivision is quicker than Adaptive QMC. but its not advisable for dof, blurry refelections.

6. Antialiasing off. jsut use it for final render

7. QMC noise threshold.. the lower the noise threshold the longer render time.. use default for test.

8. Lighting. the more lights yo have the longer render time. maximize the use of your vray sun.

9. Blurry reflection renders longers. the higher subdivision the longer time to render.

10. Shadows... more subdivision more smoother, but longer render time.

11. BUMPS are easier to use, takes shorter time to render than Displacement. jsut use displacement if necessary.

12. For final render, re-start your computer, then just press render. (sometimes su has memory leak, restarting will refresh sketchup in suing memory)

13. Alway purge your file. all those extra files takes space from your memory. Also, explode as many components as possible. Nested components might cause issues, and components also take longer to work with when reading the scene from SU.

14. Dont use caustic. calculation of caustics takes longer. jsut use caustic when you are really in with it.

15 Translucent materials takes looooooooooooooooong time to render.

16. turn off sketchup shadow, outliner and all those extra windows in Sketchup during render time.

17. when rendering always save the camera scene first. there are times you want to rerender an area which has a flaw (just render and modify that area and not the whole scene using track mouse while rendering) then stitch the two images using photoshop.. what a time saver

18. Use track mouse during render time. point your mouse to the area you want to see first. it will definitely save time. Only test an area that you are concerned about. After that, let the rendering proceed as normal. The sequence that is used is setup to minimize the amount of setup time required for each bucket by keeping parts of the same geometry from bucket to bucket. If you have buckets going all over the place, more data needs to get swapped in and out.

19. removed coplanar objects or stray lines. there are some rubies that can do this easily

sana there are some more who can share their tips and timesavers.

sir nome salamat sa tips mo...sobra nmin 'to magagamit...maraming salamat master

welcome bro....

hmm o cge sir

TIP nlang po sa SU modelling para sa mga naninibagong magmodel..

1.) pagbumibigat na hide nyo ung models na di kelangan habang nag aad pa ng other stuff such as 3ds models

2.) minsan cgro ngtataka rin kau pag naghihide ng model di na maunhide, problema nun e either asa loob ka ng group or component ng naghide ka.

3.) mas bumibilis ang pagmomodel pag nakacomponent or grouped, kasi di binabasa ng Su ung bawat edge at faces kundi as group1 grp2 ganun... di nahihirapan ang memory..

4.) mas maraming edge and faces mas bumabagal ang modelling, ganun pa man using Scenes pwede nyo hide per scene mga large models while editing some stuff pa. then sa final scene un ung complete

5.) pwede ring dahil din sa shades and shadows, mgandang off muna while modelling

6.) sometimes nagtataka kayo bakit pag nagrerender narin eh nawawala.. either dahil di mabasa ung group or kelangan magrestart, ganun paman try muna explode ung group...

7.)somnetimes may violet face sa final render.. maaring reverse face nalang un..

8.) hmmm ano pa ba...

9) isang cause ng Bugsplat eh sa pag link ng material tapos di gnamit sa model tapos pnurge unused sa paint bucket..
maari lang erase nyo sa vray material ung purged

10) pag may naalala ako ipostr nalang uli

sana may natulungan...

11) magsave!wag kakalimutan magsave...may autosave ang SU pero kapag nagrerender ka na or mabigat na masyado ung model mo off mo na baka mahirapan ka sa ginagawa mo...pero depende sa pc mo pa din...

12)wag ka gagawa or magisstore ng file kung saan ung desktop mo...sa d: gagawa or saan may malaking memory...kung may server kayo eh dun ka hack ng rendering mo...hehhehehehe,mgpaalam ka lang...

oo nga no jenaro. i have the habit of saving everything on my desktop.

just want to share my practice:

1. Model nyo muna lahat in SU at pati na rin yung mga scenes na gusto nyong i-render ( including shadow positions )

2. Backup nyo muna yung SU model na ginawa nyo bago kayo mag-render (or test renders ) sa VR.

3. Kapag naging successful na yung renders, then suddenly may changes kayong gagawin (like replacing or adding new materials), i-backup ulit yung model. It's a good practice-always BACKUP, lalo na kapag nasisira yung SU model after rendering in VR or kapag masyado ng malaki yung file at madalas mag-crash.

4. Gumagamit ako ng quick IR and LC render visopt settings just for checking the lights & shadows bago mag-render ng final using QMC engine.

excellent archfsm. tama nga naman diba.

havent tried pero well said nomer

and ung other tips mo regarding rendering is very effective and im doing it as well....... mga sir dagdag ko narin sa ibanamang gumagamit ng vray na luma. eh kabaliktaran.. kung pwede mo icomponent lahat i component mo. to save file size saka mas magrerender... ill try this noms. pag nag ka free time ako...

ganun jeff. i think i understood now why.. its about the parsing time. meron actually na ruby to put the material on top of the group para yung parsing time ng vray sa mga sketchup geometry madali. you can download it at asgvis.com

malaking tulong to ser..lalo na kpg punong puno ung scene mo!

meron ako dti tnry ko irender ng di gnagamit un ruby na un..30mins bgo bumukas un render window

after using the said ruby..naging 1-2mins nalang!

cool.

thanks sir nomer... paki explain naman po ung use nito and pano ilagay ung ruby... this should be my first time to use a ruby...
