Hey folks! (long wall of text ahead) Some time ago there was a post by Kiory about a really cool accidental discovery he had with Arma materials: https://forums.bistudio.com/topic/175495-opticalactive-camo/ And for some time I've been working on reproducing the effect and wanted to share current progress to you all since with the help of mr. zantetzou I've had some breakthrough with the technique. For background: In his post Kiory mentioned the basics on how the effect is achieved: By applying a 0 alpha (completely see through) _CA texture on the model in question and applying an .RVMAT with PixelShaderID="Refract"; and VertexShaderID="Super"; and with that I began experimenting on my own some time ago, but did not get as good results in the progress as every time, no matter what the model I applied my 0-alpha texture and my refracting material the model always had this white sheen to it. Except on the move when it looked about what I was hoping to achieve. Finally some progress: After 143 trial .RVMATs I dropped the testing in frustration as nothing seemed to change no matter what attributes I changed and couple of days ago picked up the project again after being contacted by zantetzou as he too was interested in creating "optical camouflage" material for his own project. He in his own trials had used almost identical set up with the texture and material BUT had achieved proper effect in one of the VR objects. When we exchanged our findings I too were encouraged to try out some of the VR objects and the refracting materials and ALAS for some they worked and provided identical results that Kiory had show in his video. This progress now gave me the boost to write here in hopes that others interested in the matter can partake in the trials in order to find how this works. Here is the .RVAMT i've used. 0 Alpha see through texture im sure everyone can make. Pictures: And here are couple of screenshots on how it looks after application on different models: Before: After: Theorizing: Notice the difference between the VR objects on the left and my test man with different material combos on the right. The white sheen is obvious and something that happen on all other objects me or zantetzou have tried but the VR objects the effect is working (maybe it works "wrong" on them in a way, but it looks the like what we would like to use) but so far I have not figured out why. Currently I've theorized that whatever the texture/material combo the model originally has somehow affects how the refracting shader works on them and thus I have extracted the texture/material paths applied on the VR objects via hiddenSelectionsTextures[] and hiddenSelectionsMaterials[] in their configs and tried to apply the same ones on my test man in the pictures. This however did not produce the any results and so I am here asking if anyone else has ideas on how to proceed from here. I've been considering the possibility that man character is drawn somehow different from static objects and as my next step I will make a static test object to see if theres any difference there. For some reason the white sheen also disappears in some angles and when the object is looked at from high speed, or the objects moves fast: Shot this one when running past the testman: Known objects it works on: So far following objects have show the refracting shader as in the picture on the left: Sphere (200cm) / Sign_Sphere200cm_F VR Wheeled APC Target / Land_VR_Target_APC_Wheeled_01_F VR Tank Target / Land_VR_Target_MBT_01_cannon_F VR MRPA Targetr / Land_VR_Target_MRAP_01_F VR Wall / VR_Billboard_01_F Thanks for reading this far: And I would suspect that it would work on some other VR objects like the sphere that are somewhat see through/emmisive to begin with. I will continue working on this since I really want to make a scifi optical camouflage ghillie suit for our mod and eventually when we get back to our C&C mod this effect would be quite essential for Nod Stealth Tanks. If you get any ideas on what makes this work, don't hesitate to post on this thread!
