Hi guys,
I've just got back into 3d max and decided to start using vray and HDRI. I put my backplate in, set my cameras etc, Then I try to put the actual hdri into the environment slot. When I try to do this it comes up with "image I/O error" it states the file location then underneath "memory error". I know the hdri files are pretty big but my computer isnt too bad.( Im running intel i7 quadcore and 4gb ram). Any suggestions as why this is happening and is there a way around this problem. Thanks in advance
I see you already post same question from other thread ---> Here
So I am going to answer your question here since its the correct place to ask. First, what is your PC specs? Does your PC have sufficient memory to handle scene (Object level of mesh density), HDRI and backdrop?
Obviously message you re getting is because your system cannot handle this memory, The HDRI and Backdrop contain Large size and would generally take up lot memory. Including your object/scene. Normally, its a frequent problems for 32bits OS. So three solutions for you:
1) Switch/Change your window in/to 64 bit, and add extra memory (Up to 8gb or more depending on your motherboard).
2) Reduce size of HDRI or Backdrop with any photoedit software. (It probably would drop down HDRI and backdrop quality)
3).Forget HDRI and Backdrop... create your own background scene.
Number 1 or 3 usually would be best solution for everyone

Hope that helps....
Thanx for getting back to me equiNOX. The machine I just purchased is 32 bit and the rest of the specs are in the first post.
Obviously cant afford to upgrade just yet, was just suprised the computer couldnt handle the hdri+scene.
For now I think I would just like to reduce the massive hdri file size in photoshop.
I tried to do this the same way you would reduce a jpeg / save as >change quality. But without success as it doesnt give you the option. I have searched for help with this but without success. so if anyone could help that would be great.
Do you have Post-production or Photoedit software such as Photoshop, After Effect, Fusion, Combustion, or etc?? If so....
Here what I would do if I m in your situation...
I would reduce HDRI size down a little bit... (Since HDRI is not very much recognized unless you use 100% reflected material)
create duplicate background image of your preference, one would be in small size to reduce, and other one would be at original size. The smaller image would be good for background reference, where you could align, adjust your object to fit background inside 3ds max viewport. (But do not render with it).
Render your object with Layer Pass, Diffuse w/reflection, A.O., Shadow, and etc matching the original image size.(Yes, the background would be black.) Save all of passes in .PNG format so you would have alpha background also won't lose quality.
Run any Post Production software, Open Original background of your preference and Open All of layer passes and make composite of each passes onto original background images.
It may be long and painstaking process... but better than nothing... I used these steps on 32-bit laptop that runs with 2g memory and duo processors when I'm traveling. I always get statified results
Hey EquiNOX, Thanks again for the advice, I will look into your way of rendering out . My way would be to reduce the HDRI down so max could handle it. Then put it into a vray light and environment reflections with the backplate in the viewport only. However im geting problems with the glass reflection being too harsh and not enough opacity , so looks like a few more test renders and some serious aftercare in photoshop. I will upload some test pics later. Thanks again EquiNOX.
Always add thickness on a flat geometry to get better transparent effect using VRayMaterial (I am sure it applies to all type of render materials too). You could do by add shell modifier then collaspe or duplicate flat geometry and filp it opposite side. The thinner flat panel is -- the more transparent it become --the less reflection it produces. "Almost invisible" or depending the IOR you have set up, strange effect it shows, the more IOR it appears.
In real life, compare the transparent sheet (one used for overhead projector) to real Glass that has thickness....Hope that light above your head do glare

Managed to fix the windscreen problem. You where right, I had the windscreen shelled out, so took that off and seemed to improve the opacity. Cheers
