Sharp image

[3form]

Hi All

Is it just me or is the standalone render more crisp / sharp then the 3ds max plug-in. I know its the same engine, but just doesn't look nice and sharp. I have checked and aperture is set to 0. Here is a WIP to show you. Been cooking for 8H and still not very sharp.

Cheers

put the resolution up & play with HotPixel removal (imager) & Filter size (kernel) - these two cna help to get rid of noise, but they do make You image more blury.

Hi,

what´s about the Pixelfilter?
Try triangle or mitchel with value of 1.1 (didn´t remember if mitchel is available in Octane).

Octane hasn´t pixel filter, only a filter size which will blur the image if the value is higher then 1.0.
Box, triangle, gauss, mitchell and lanczos are mental ray filters.

reading a manual to get known the program is advisable before starting questioning same questions on forum, that been already answered - You might get surprised, but You can find answer very fast - manual itself is not too long (it's not like 1000+ pages of unofficial vray manual). You get quite some ideas (talking from personal perspective) from time to time remembering some functionality in Octane. We are used to repeat known ste=eps, over and over, but if You want to move ahead, need to push a bit.

Both of mentioned parameters could be used as a tool to get out some sharpness from image and some unwanted artifacts. Fireflies could be removed efficiently without any need of baking image for extended hours. So even if it sounds a bit paradoxal, sometimes pushing up resolution and putting some bluriness might lead to faster output =) wrote a bit 'bout that latelly (check the signature) You can download some scene files too, if You'd liek to play Yourself.

Thanks for the help!

Will try and ply with the filter size. I need to dig out a scene that I have rendered both in Standalone and 3ds max to show the comparison. They both baked for the same amount of time and all the setting were the same but the standalone was def sharper crisp nice edges in scene. Or I could just be going crazy.

I am sorry, but reading the questions before starting to answer will also help.
3form question was about the sharpness of the image, not about the noise or render speed.
Just want to put the attention to the filter size, and yeah, it´s not pixel filter, well i am using a bunch of 3D-Software and didn´t had access to Octane when i was writing.

Sharpness does depend on resolution, too, isn't it? (Where from You get details if You don't have the resolution to capture them?) Some are afraid of putting up resolution, because that will lead to higher rendertimes (which is not true 'because You can play with parameters to help You getting rid the noise, but leaving the details). So..everything is conected. Balance is a key =)

i agree, BUT:
back then i used to work with Lightscape, a complex light analysis and radiosity software.
it was able to render super sharp images. Then Autodesk took over, killed the standalone and "integrated" it into 3dsmax` Radiosity engine. From that moment on sharpness was gone. Images rendered out of 3dsmax looked blurry, no sharp edges;
images looked a little bit like the image posted by 3from...
i am not an image filter expert but this image is NOT sharp.

Default filter size is 1.5, so try to turn it down to 1.0 post the image again.

i never did a direct comparison between Standalone and Plugin but i am VERY curious about it!

i guess rendertime / cookingtime has nothing to do with sharpness. time decreases noise & fireflies. so do filtersize and hotpixel removal. yet: filtersize and hotpixel removal cause blurriness, so they are best applied on x2 or x4 image reesolution. in favour of sharpness i would try to set filtersize to 1 and deactivate hotpixel removal.
