Thank you, I appreciate it!

You bring your HDRI into the Material editor before you use it in your skydome. because now you can rotate the hdri in the material editor.

To fix that there is a lot of possible solutions. Make the exposure value really small and check again. Increase the intensity of the light 10 times and check again. Check if the light is not inside a wall. Check if the camera is inside a wall.

I had this same problem and I figured that it happened because of the downloaded scene. The scene was too big, so I scaled it down are readjusted the camera and lights, and it worked.

Хотя я ничего не понимаю по-русски! Большое спасибо за ваш комментарий.

sorry, I don't have one.

With an arnold light and the IES information of s table lamp. Some manufacturers provide the 3d models of their lams snd the IES files fir the light distribution.

Sorry for the typos

Every face (triangular element) has a front side that is visible and a backside tha is invisible. So maybe something that looks like itbis not there is just flipped.

Placing materials with textures on objects works the same way in every renderengine. I have tried to show a few ways in 2 videos. (UVW Map modifier, Unwrap UVW)

With Arnold Lights you do not exclude objects from the light itself, but you tell the object not to receive certain rays of light or shodows or anything like that. Select the object and apply the "Arnold Properties" modifier. Here you can select or deselect whatever you need. Good luck.

Hi, there are several things you wantvto check: materials: give everything in your model a material that is compatible with Arnold and render again. EV: use am extremely low exposure value (2) in you camera and render again. Select the glass and hide it temporarily, maybe its blocking the light. Scale: check if the size of the model fits the units defined under customize-units setup. Sounds funny, but is thereba chance that either the camera or the light is inside of an object? Wall, floor ... Those are the most likely reasons.

I can only use, what comes with the program.

@@AFTutorials New UI Icons every year you mean ) but i understand you.. Great tutorial anyway!

Arnold's dome light and physical sky are super noisy on interior renders, so if you were hoping for clean interiors using them yes, render times would be stupid. Instead you have to use the distant light for the sun and light the interior with quads. Avoid lighting through glass (i.e. window) as that increases noise but if you have a backlit room like in this example you can have a quad just outside and light link it so it only affects the glass and not the rest of the interior. It's also super easy to over sample with Arnold particularly if you increase the diffuse rays trying to clean up the GI. Using Arnold's adaptive sampling and changing the threshold (the default is too much) helps clean noise a lot. Also using the newer Global Light sampling feature can also shave off render time. Lastly using Arnold's Noice de-noiser will clean up the image nicely. Ultimately it just depends on what you prefer. Corona is super easy and and good out of the box, just add a sun and sky and you're good to go. If you want to be a bit more hands on then Arnold works to.
