rendering in alias studio tool!

[lalla]

Hello everyone! I would have a question if you can help me! I often happen that when I have a new job and launch the first renderings in raytracer the program works well even at high resolution of the image then (maybe even the next day) after the third or fourth rendering the pc slows down a lot, i.e. puts the beauty of 2 hours to make a rendering that first made me in 15 minutes and frankly I do not explain why...

1) check the lights. There are some types of lights that slow the calculations. Consider that when you cast a shade, if there are no active lights he creates some standards that then remain there

2) check the surfaces. . attention to cleaning, always!

3) verify file size. If they grow in dismeasure it means that there is some porcade that is not known, but there is, and it is rendered.

Moreover, in globals are you sure you have removed the tipping to "reverse to v9.0 tesselator"?

 

[lalla]

So...the first things should go well since I didn't touch the file and first it throws it normal....and after without adding lights and surfaces becomes lentissim so I don't think it depends on these things....while at the tipping I didn't notice... but I checked now and it didn't come out so it shouldn't even be that problem....:frown:

image size? always the same? Are you sure?
sometimes opening multiple files at the same time the rendering settings are updated.

added some background? some particularly reflective material?

 

[lalla]

Then it's likely. ..because adess I don't remember with precision...that I have changed slightly qulalche reflectance of the floor (which is a normal floor with a projection grid added) the problem is that with esattezz now as now I don't know what parameters I touched because as you know well every direct make changes something before launching the final rendering anyway I don't seem to have added anything so absurd to slow down so... or anyway ask just why

 

[Fulvio Romano]

that tell you... if you can do it, mail the file and try to understand something more.

However in the future you should save the file that works, then it just doesn't work anymore, save it with another name and store it. so sooner or later you know what the problem is.

However, unless you use the volumetric lights that plant any machine, in general the major slowdowns you have when you have two facing surfaces, both reflective. you can set up, but now I do not remember where, the maximum number of reciprocal reflections that are calculated. if this value is too high, theoretically, the render may not end anymore.

 

[lalla]

At the moment I tried to reduce surfaces that I had designed to do as a background and it actually goes much better!!!if the situation is not better I try to post the file!! Meanwhile I really thank you for the help and interest...in any case I was very helpful!! thank you really!!:biggrin:

If the alias forum started to pop up a bit, it would be a holy thing.

for the bottom, if you can, use lambert materials and not blinn. Anyway for "background" I meant the active one that sets up along with the materials... now I don't have the name...

 

[lalla]

talk about the environment?ok ok...it is that very often I need the blinn for the reflections that from and so...
If you talk about alias studio tool you know is unpopulated because unused or am I wrong? in fact it is difficult to find info about this program... but purtropp teach us this...eh eh

hi lalla, use alias for 14 years and I learned a simple thing: too many rendering parameters. I mean that the settings are infinite and microscopic, and it is counterproductive to spend a day setting them all and then to expect a result that will hardly be the desired one. and then start again.

I have no idea what kind of rendering you are making, but there are external rendering engines that do an egregio job, faster, and with better results than the internal rendering engine. I suggest you try this alternative, you save a lot of time.
