Hi I apologize for reviving an old post, but I'm not sure how to start a new one in a relevant group. I can't seem to find a discussion group on Maxwell Render either. The technical issue I face - When I apply an emitter material on a grouped object, and I flip/mirror this object, the emitter fails to work. [image: 0J7H_z_emiiterissue.jpg] In the attached picture, "A" shows the original group. Emitter works fine. "B" shows the original grouped copied to the left. Emitter works fine too. "C" shows the copied group on the left flipped horizontally. Emitter blacks out. Is anyone else facing this same issue? Wondering if there's a workaround for this. This issue caused problems when I'm rendering cars. One headlight emits light, but the headlight on the flip side of the car does not light up. I tried exploding, regrouping, making the component unique, reapplying emitter texture to the flipped group - nothing worked so far. But this problem doesn't seem to affect other textures, like the red paint I applied in the demo cube shown in the above attached image. I'm using Mac OSX 10.10.5, Sketchup 2016, Maxwell Render 3.2, on Mac Pro 5,1. Any advice would be greatly appreciated! Best regards

Thanks for the tips guys. I couldn't (and can't) post an image of the final result, since there's some secretkeeping of the design involved for now. Perhaps in a few months. Anyway, the biggest problem in this story was mainly the guy who commissioned it didn't quite know what he wanted and inadvertently took it out on me, telling me every time I had rendered something, that it looked wrong. Finally we settled for using a really plain, modelled plank, just plain colour and a simple groove. Thanks for the link Valerostudio, to that arroway thingy. I'm sure it will be useful in a later project I knew the site of course, but I just found out this time around that they have downloadable samples. Quite a handy thing, especially with the people I work with... always changing their minds... As to the creating of bump maps etcetera; I'm quite adept at that already, but it's a nice video to watch nonetheless. Always a pleasure to see someone working at something they're good at.

Hello thanks for responding. I didn't have the time to work it out so I used ies lighting instead.

A cheat if you just need color is to put the color directly on the refraction. you won't get the SSS effect but on box this may not matter much.

thank you very much for these background informations jason! people can always count on your maxwell knowledge here...much appreciated!

As a side note, I would suggest getting Onyx Tree for making trees. Especially if you want a hi-poly version for MXS and then export a very low poly version for SKP or even better, it will export shaded TGA which you can turn into a PNG file to save even more memory in SU. Using the new MXS reference feature it kicks serious butt. The Onyx program, although it looks dated is very powerful, will let you create tons of custom trees and shrubs and they export in 3DS, OBJ, FBX and other formats. Well worth the money. I think it was like $150 for the Broadleaf program and I feel like I have already created well over $150 in tree models. Highly recommended for sure for all SketchUpers.

my problem solved! by uncheking "use for glossy rays" in "light cache" in V-ray option

ah.. ok.. i quick googled it and found the "official reseller" edit: removed the pirate torrent link (sure.. i didn't want to promote it, just kidding.. anyway..)

Blender what else ? Cycles http://www.youtube.com/watch?v=LyMZ8JG9Yqs Internal renderer! http://www.youtube.com/watch?v=0wVYwKxT0Cs

If you are loading a vispot from the internet, I would say thats the culprit. You should stay away from these things because some are from the older 1.05.30 version and there are lots of changes between the 2 versions and will cause errors.

Do bear in mind you have created a scene where there are many more bounces to resolve than normal (by virtue of having mirrors reflecting into each other -- AGS is just a metal mirror with reduced opacity) -- this will take time to resolve and as I said SL 18 would be the minimum I would personally accept as "final". Best, Jason.

@vizfellas said: Try this Make modeling in mm scale. When you add light in VRAY option increase power to 1000 of the IES file. OMG! Thanks so much for this info, it was such a simple fix, my IES lights are showing now. Thanks!

FIXED! I guess I deleted the plant while batch render was in progress. I just had to stop the rendering process, delete it again, purge unused materials, save and close. When I re-opened the model and did a test render, the plant was gone... hopefully forever. Thanks anyway... hope this can still be helpful for someone Thanks, Ed

Most likely this is an emitter/instancing issue -- disable "use instances" to check. Also, you should probably update to the newest version of Maxwell and see if that clears the issue up. Best, Jason.

@jonedvard said: oh and regarding the spheres. my approach would be to increase the number of segments when creating your sphere - providing a smoother surface. an arc with about 48 segments is what i generally use for a fairly adequate smooth surface. hope that helps! It's called the "terminator" problem @ATLAStudio - good info, thanks! For me, I just keep re-loading a working water vismat, so I didn't remember off-hand which setting it was...

That most likely can be fixed by changing your irradiance map settings. There's an option to "Check sample visibility" that you can enable. You can also increase your "Max rate" to -1 or 0. Lastly, you can increase your HSph. Subdivs to 70 or 90 - which helps with splotchy shadow areas. Worst comes to worst, you can enable Detail Enhancement, but that means longer render times.

Have you tried the Advanced Camera Plugin. See here It might be of use to you. Rob

thanks guys. i'll look into it. now i know what the subdivide tool functions as. all this new terminology by way of v-ray! i did acquire sketchuv recently - and really need to sort & figure out it's features. all the best!
