pitapan Posted November 15, 2018 Share Posted November 15, 2018 Hello! I'm trying to control frequency of Cellular noise with distance from the middle of the UV map. There is some weird distortion on the noise, and I'm quite sure now my whole approach to this is wrong. Any ideas how this could be achieved? Thanks in advance cell_noise_freq_by_rad.hiplc Quote Link to comment Share on other sites More sharing options...
bobbybob Posted November 16, 2018 Share Posted November 16, 2018 (edited) Try using the position for calculating the length. If you create an attribute vop and use the UV as the color (at sop level), you can see why you are getting this distortion.

pitapan Posted November 16, 2018 Author Share Posted November 16, 2018 Hello, thanks for the reply. The is no distortion in the UV at all, it's a simple planar projection (see the file for that). My circle is has radius of 1, is placed in 0,0,0. I measure the length of P and feed it to freq. Same results. See screenshot for VOPs version.

pitapan Posted November 16, 2018 Author Share Posted November 16, 2018 I'm guessing the frequency of Cellular Noise is calculated in conjunction with UV map itself as the distortion is pointing in the UV corner where values are [0,0]. Hmm.... Quote Link to comment Share on other sites More sharing options...
