I’d like to change from 1.09 to 1.45. I have some works in progress. The 1.09 version works fine for me, but I know that lightmap is faster and better at second bounces. I’ve got a few questions: 1) Would you recommend the 1.45 version? or do u think it has too many bugs? (Since I’ve got a strict deadline for my work, I can’t waste my time in trying to solve bugs problems) 2) Are the two versions compatible or do I need to re-set the values? (material and lights) 3) Can I install 1.45 without deleting the 1.09 version? Thanx in advance. fabrizio ---

Id recommend you not change versions. I think most would agree. ---

I agree with percydaman, during productions do not switch software or renders. However from previous experience transfering from older versions of vray to new ones has been no problems. vray 1.457 seems to be less buggy then any other versions, plus all the new features. ---

You should never change any part of your software during a project … you just never know .. wait till your project ends then have a play with it. ---

yeah I agree…don’t change renders in mid production…I keep 1.09 around for oder projects started w/ that, and I use 1.45 for any new project…I tried using 1.45 on a 1.09…it was a bad idea. ☹ 1.45 just simply stoped in the middle of the rendering…the scene was fairly simple, and I never had the time to investigate what the issue/s were, but I think is wise not to mix things up 😉 paul. ---

Like the others say, don’t switch _during_ a project. However, if you are between projects I would reccomend trying it out. I’ve switched to 1.45.70 for production work here and would never want to go back to 1.09.03n now. ---

no way i would go back to 1.09. this works fine because we do usualy rather smaler projects that are easier to handle as big productions. but the lightmap alone is worth it. 😄 Tom ---

updrade to viz2005 then you can use 1.45 as it is the equivalent of max6 I havnt really used the new features much in viz2005 yet but look through the list of changes and you may see some worth in it (even if you just want to be able to use lightmapping!) ---

re I had no problem switching over although I did not switch in the middle of a project. I had no problems with bringing projects from 1.09 over. Just upadted my materials and started using the lightmap for a 2nd bounce. ---

The only thing why we switched back here is that the irradiance map viewer is not compatible with 1.45. So, impossible to merge our solutions ☹ ---
