Cameras and HDRI in Arnold - Getting Started in 3DS Max 2021 (part 7) 

Thank you very much! I appreciate your feedback.

Thank you very much!

Maybe you have moved the camera after you have applied the auto tilt correction and it does not update automatically. maybe re-apply it and it will work correctly.

3DS Max uses sn Alpha-Channel, that is a grayscale image channel (just like the red, green and blue channel) to seperate foreground from background. If you save the image in certain image formats (i recommend TIF ) the alpha channel is included. If you preview the image, the alpha channel is in some file formats shown in white removing the background. Open the image for example in Photoshop and you will see, that the background is still there. If you don’t need the alpha channel you can also nit include it when you save the TIF image. (I do not recommend that. If you change your mind you have to re-render everything) 😜

@@AFTutorials Thank you for your reply. The white background is only in png image, in al the other formats it shows regularly the background. But the strange thing is that it does only in one of the files that i saved and it does not in other files, probably I have done something wrong in that file !!! . From your videos i learned that you prefer tif and i respect your opinion and experties. Now i watch (part 9) of your videos, are a great help to me. I follow them step by step and practice all the way through.Thank you again.

I am a big fan of PNG files too, but not for renderings. I usually use TIF or EXR If you use a PNG and you include the "Alpha Channel" when you save it, it will make the alpha channel transparent right away and show the background as white. So there is no way to get the background back. The TIF format doesn't do that.

The grainy (or noisy) renderings mostly come from any low sample settings in both the render setup window or in the parameters of every light you are using. In the Arnold lighting videos I am explaining how to fix that. I think you should check out the interior lighting. Good luck.

@@AFTutorials Ahh yeah the IBL settings in the Arnold tab was exactly it! It was set to 1, having at at least 2 or 3 is fantastic. I had no idea that's where that was hidden. Thanks! I do E-Learning courseware for the military and we've recently swapped to max from a version that used Mental Ray to Arnold :) Look forward to more tutorials.

You don‘t necessarily need Sketchup, but you would need the Sketchup File. Max imports that quite well.

I can not answer that question, The speed of your rendering depends on so many different settings that I can not help you there.

Try to save it in SketchUp as an older version, that might help. It is also possible, that sketch up lines are not recognized by 3DS max. Try polygons first. That works for sure.

@@AFTutorials saving the file in older version works. thank you for your reply. this is a great help. Also, i have been following your entire 3dsmax tutorial series and i learned the software as a beginner in 1 day. You are a great teacher! Thank you so much.
