Don't see a crosshair in a game?

[CyberDemon]

First make sure your Color Mask in the program settings has non-zero Alpha value (transparency). Full opaque = 255, full transparency = 0.

Some games require a few additional actions to get visible overlay. If this list doesn't help you, please send a message to support from our web site https://hudsight.com or in this community.

CSGO

A several months ago the Trusted Mode was added in CSGO as a new anti-cheat measure. It is enabled by default. Any third-party programs do not work in this mode. To show the crosshair, you need to open the CSGO launch options (in properties) and add the following key:

-allow_third_party_software

FiveM - the GTA V multiplayer mod

If the game render type set to DirectX 10 or DirectX 10.1, then you will not see our crosshair in FiveM (but original GTA5 works good). Try to change this option to DirectX 11 (Game settings -> Graphics)

Destiny 2

It is not possible to get overlays working with Destiny 2, because game developers use their own special anti-cheat which has a very short white list and we're not in this list.

Rainbow Six - Vulkan

Unfortunately, R6 devs are blocking 3rd party Vulkan layers (we use our own layer to draw overlays in Vulkan-powered games). But there is a workaround to make our layer "eligible" :)
Open software installation folder and subfolder Tools (check a screenshot).

Then open playclawvk64.json in any text editor, find the "name" parameter and change its default value from "VK_LAYER_playclaw" to "VK_LAYER_RENDERDOC_Capture", save the file, run the game.

What we have done? We have changed our layer name to white-listed layer name of RenderDoc software. This software is used by game developers and probably you will not have it and no conflict is expected.
